'hid_hw_stop()' is already in the error handling path when branching to
the 'hid_hw_open_fail' label.
There is no point in calling it twice, so remove one.

The `connected` value for wired devices was not properly initialized,
it must be set to `true` upon creation, because wired devices do not
generate connection events.
When a raw client (the Steam Client) uses the device, the input device
is destroyed. Then, when the raw client finishes, it must be recreated.
But since the `connected` variable was false this never happended.

Newer Logitech mice report their battery voltage through feature 0x1001
instead of the battery levels through feature 0x1000.
When the device is brought up and we try to query the battery, figure
out if it supports the old or the new feature. If it supports the new
feature, record the feature index and read the battery voltage and
its charge status. The device will respond with three bytes: the first
two are its voltage, and the last one is a bitset, reporting if the
battery is charging, fast or slow, in critical level or discharging.
If everything went correctly, record the fact that we're capable
of querying battery voltage.
Note that the protocol only gives us the current voltage in mV.
We store that as-is, but when queried, we report it in uV as
expected by sysfs.
Like we do for other ways of interacting with the battery for other
devices, refresh the battery status and notify the power supply
subsystem of the changes in voltage and status.
Since there are no known devices which implement both the old and the
new battery feature, we make sure to try the newer feature first and
only fall back to the old one if that fails.

This patch allows short reports to be translated into long reports.
hidpp_validate_device now returns a u8 instead of a bool which represents
the supported reports. The corresponding bits (i.e.
HIDPP_REPORT_*_SUPPORTED) are set if an HID++ report is supported.
If a short report is being sent and the device does not support it, it is
instead sent as a long report.
This patch also introduces support for the MX Master (b01e and b012).

The open method of hiddev handler fails to bring the device out of
autosuspend state as was promised in 0361a28d3f9a, as it actually has 2
blocks that try to start the transport (call hid_hw_open()) with both
being guarded by the "open" counter, so the 2nd block is never executed as
the first block increments the counter so it is never at 0 when we check
it for the second block.
Additionally hiddev_open() was leaving counter incremented on errors,
causing the device to never be reopened properly if there was ever an
error.
Let's fix all of this by factoring out code that creates client structure
and powers up the device into a separate function that is being called
from usbhid_open() with the "existancelock" being held.
Fixes: 0361a28d3f9a ("HID: autosuspend support for USB HID")

The Acer SW5-012 2-in-1 keyboard dock uses a Synaptics S91028 touchpad
which is connected to an ITE 8595 USB keyboard controller chip.
This keyboard has the same quirk for its rfkill / airplane mode hotkey as
other keyboards with the ITE 8595 chip, it only sends a single release
event when pressed and released, it never sends a press event.
This commit adds this keyboards USB id to the hid-ite id-table, fixing
the rfkill key not working on this keyboard.

The syzbot fuzzer found a slab-out-of-bounds bug in the HID report
handler. The bug was caused by a report descriptor which included a
field with size 12 bits and count 4899, for a total size of 7349
bytes.
The usbhid driver uses at most a single-page 4-KB buffer for reports.
In the test there wasn't any problem about overflowing the buffer,
since only one byte was received from the device. Rather, the bug
occurred when the HID core tried to extract the data from the report
fields, which caused it to try reading data beyond the end of the
allocated buffer.
This patch fixes the problem by rejecting any report whose total
length exceeds the HID_MAX_BUFFER_SIZE limit (minus one byte to allow
for a possible report index). In theory a device could have a report
longer than that, but if there was such a thing we wouldn't handle it
correctly anyway.

When polling a connected /dev/hidrawX device, it is useful to get the
EPOLLOUT when writing is possible. Since writing is possible as soon as
the device is connected, always return it.
Right now EPOLLOUT is only returned when there are also input reports
are available. This works if devices start sending reports when
connected, but some HID devices might need an output report first before
sending any input reports. This change will allow using EPOLLOUT here as
well.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.5 kernel cycle
Core changes:
- Expose pull up/down flags for the GPIO character device to
userspace.
After clear input from the RaspberryPi and Beagle communities, it
has been established that prototyping, industrial automation and
make communities strongly need this feature, and as we want people
to use the character device, we have implemented the simple pull
up/down interface for GPIO lines.
This means we can specify that a (chip-specific) pull up/down
resistor can be enabled, but does not offer fine-grained control
such as cases where the resistance of the same pull resistor can be
controlled (yet).
- Introduce devm_fwnode_gpiod_get_index() and start to phase out the
old symbol devm_fwnode_get_index_gpiod_from_child().
- A bit of documentation clean-up work.
- Introduce a define for GPIO line directions and deploy it in all
GPIO drivers in the drivers/gpio directory.
- Add a special callback to populate pin ranges when cooperating with
the pin control subsystem and registering ranges as part of adding
a gpiolib driver and a gpio_irq_chip driver at the same time. This
is also deployed in the Intel Merrifield driver.
New drivers:
- RDA Micro GPIO controller.
- XGS-iproc GPIO driver.
Driver improvements:
- Wake event and debounce support on the Tegra 186 driver.
- Finalize the Aspeed SGPIO driver.
- MPC8xxx uses a normal IRQ handler rather than a chained handler"

Pull clk updates from Stephen Boyd:
"This merge window we have one small clk provider API in the core
framework and then a bunch of driver updates and a handful of new
drivers. In terms of diffstat the Qualcomm and Amlogic drivers are
high up there because of all the clk data introcued by new drivers.
The Nvidia Tegra driver had a lot of work done this cycle too to
support suspend/resume and memory controllers. And the OMAP clk driver
got proper clk and reset handling in place.
Rounding out the patches are various updates to remove unused data,
mark things static, correct incorrect data in drivers, etc. All the
little things that improve drivers and maintain code health. I will
point out that there's a patch in here for the GPIO clk driver, that
almost nobody uses, which changes behavior and causes clk_set_rate()
to try to change the GPIO gate clk's parent. Other than that things
are fairly well SoC specific here.
Core:
- Add a clk provider API to get current parent index
- Plug a memory leak in clk_unregister() path
New Drivers:
- CGU in Ingenix X1000
- Bitmain BM1880 clks
- Qualcomm MSM8998 GPU clk controllers
- Qualcomm SC7180 GCC and RPMH clk controllers
- Qualcomm QCS404 Q6SSTOP clk controllers
- Add support for the Renesas R-Car M3-W+ (r8a77961) SoC
- Add support for the Renesas RZ/G2N (r8a774b1) SoC
- Add Tegra20/30 External Memory Clock (EMC) support
Updates:
- Make gpio gate clks propagate rate setting up to parent
- Prepare Armada 3700 for suspend to RAM by moving PCIe
suspend/resume priority
- Drop unused variables, enums, etc. in various clk drivers
- Convert various drivers to use devm_platform_ioremap_resource()
- Use struct_size() some more in various clk drivers
- Improve Rockchip px30 clk tree
- Add suspend/resume support to Tegra210 clk driver
- Reimplement SOR clks on earlier Tegra SoCs, helping HDMI and DP
- Allwinner DT exports and H6 clk tree fixes
- Proper clk and reset handling for OMAP SoCs
- Revamped TI divider clk to clamp max divider
- Make 1443X/1416X PLL clock structure common for reusing among i.MX8
SoCs
- Drop IMX7ULP_CLK_MIPI_PLL clock, it shouldn't be used
- Add VIDEO2_PLL clock for imx8mq
- Add missing gate clock for pll1/2 fixed dividers on i.MX8 SoCs
- Add sm1 support in the Amlogic audio clock controller
- Switch some clocks on R-Car Gen2/3 to .determine_rate()
- Remove Renesas R-Car Gen2 legacy DT clock support
- Improve arithmetic divisions on Renesas R-Car Gen2 and Gen3
- Improve Renesas R-Car Gen3 SD clock handling
- Add rate table for Samsung exynos542x GPU and VPLL clks
- Fix potential CPU performance degradation after system
suspend/resume cycle on exynos542x SoCs"

Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
"As part of the cleanup of some remaining y2038 issues, I came to
fs/compat_ioctl.c, which still has a couple of commands that need
support for time64_t.
In completely unrelated work, I spent time on cleaning up parts of
this file in the past, moving things out into drivers instead.
After Al Viro reviewed an earlier version of this series and did a lot
more of that cleanup, I decided to try to completely eliminate the
rest of it and move it all into drivers.
This series incorporates some of Al's work and many patches of my own,
but in the end stops short of actually removing the last part, which
is the scsi ioctl handlers. I have patches for those as well, but they
need more testing or possibly a rewrite"

"Highlights:
- Infrastructure for secure boot on some bare metal Power9 machines.
The firmware support is still in development, so the code here
won't actually activate secure boot on any existing systems.
- A change to xmon (our crash handler / pseudo-debugger) to restrict
it to read-only mode when the kernel is lockdown'ed, otherwise it's
trivial to drop into xmon and modify kernel data, such as the
lockdown state.
- Support for KASLR on 32-bit BookE machines (Freescale / NXP).
- Fixes for our flush_icache_range() and __kernel_sync_dicache()
(VDSO) to work with memory ranges >4GB.
- Some reworks of the pseries CMM (Cooperative Memory Management)
driver to make it behave more like other balloon drivers and enable
some cleanups of generic mm code.

Pull pipe rework from David Howells:
"This is my set of preparatory patches for building a general
notification queue on top of pipes. It makes a number of significant
changes:
- It removes the nr_exclusive argument from __wake_up_sync_key() as
this is always 1. This prepares for the next step:
- Adds wake_up_interruptible_sync_poll_locked() so that poll can be
woken up from a function that's holding the poll waitqueue
spinlock.
- Change the pipe buffer ring to be managed in terms of unbounded
head and tail indices rather than bounded index and length. This
means that reading the pipe only needs to modify one index, not
two.
- A selection of helper functions are provided to query the state of
the pipe buffer, plus a couple to apply updates to the pipe
indices.
- The pipe ring is allowed to have kernel-reserved slots. This allows
many notification messages to be spliced in by the kernel without
allowing userspace to pin too many pages if it writes to the same
pipe.
- Advance the head and tail indices inside the pipe waitqueue lock
and use wake_up_interruptible_sync_poll_locked() to poke poll
without having to take the lock twice.
- Rearrange pipe_write() to preallocate the buffer it is going to
write into and then drop the spinlock. This allows kernel
notifications to then be added the ring whilst it is filling the
buffer it allocated. The read side is stalled because the pipe
mutex is still held.
- Don't wake up readers on a pipe if there was already data in it
when we added more.
- Don't wake up writers on a pipe if the ring wasn't full before we
removed a buffer"

Pull hmm updates from Jason Gunthorpe:
"This is another round of bug fixing and cleanup. This time the focus
is on the driver pattern to use mmu notifiers to monitor a VA range.
This code is lifted out of many drivers and hmm_mirror directly into
the mmu_notifier core and written using the best ideas from all the
driver implementations.
This removes many bugs from the drivers and has a very pleasing
diffstat. More drivers can still be converted, but that is for another
cycle.
- A shared branch with RDMA reworking the RDMA ODP implementation
- New mmu_interval_notifier API. This is focused on the use case of
monitoring a VA and simplifies the process for drivers
- A common seq-count locking scheme built into the
mmu_interval_notifier API usable by drivers that call
get_user_pages() or hmm_range_fault() with the VA range
- Conversion of mlx5 ODP, hfi1, radeon, nouveau, AMD GPU, and Xen

git://people.freedesktop.org/~thomash/linux into drm-next
Graphics APIs like OpenGL 4.4 and Vulkan require the graphics driver
to provide coherent graphics memory, meaning that the GPU sees any
content written to the coherent memory on the next GPU operation that
touches that memory, and the CPU sees any content written by the GPU
to that memory immediately after any fence object trailing the GPU
operation is signaled.
Paravirtual drivers that otherwise require explicit synchronization
needs to do this by hooking up dirty tracking to pagefault handlers
and buffer object validation.
Provide mm helpers needed for this and that also allow for huge pmd-
and pud entries (patch 1-3), and the associated vmwgfx code (patch 4-7).
The code has been tested and exercised by a tailored version of mesa
where we disable all explicit synchronization and assume graphics memory
is coherent. The performance loss varies of course; a typical number is
around 5%.

Pull RISC-V updates from Paul Walmsley:
"New features:
- SECCOMP support
- nommu support
- SBI-less system support
- M-Mode support
- TLB flush optimizations
Other improvements:
- Pass the complete RISC-V ISA string supported by the CPU cores to
userspace, rather than redacting parts of it in the kernel
- Add platform DMA IP block data to the HiFive Unleashed board DT
file
- Add Makefile support for BZ2, LZ4, LZMA, LZO kernel image
compression formats, in line with other architectures
Cleanups:
- Remove unnecessary PTE_PARENT_SIZE macro
- Standardize include guard naming across arch/riscv"
