Sometimes USB hosts can ask for buffers that are too large from endpoint
0, which should not be allowed. If this happens for OUT requests, stall
the endpoint, but for IN requests, trim the request size to the endpoint
buffer size.

Ethtool ring feature has _max_pending attributes read-only.
Set only read-write attributes in nsim_set_ringparam.
This patch is useful, if netdevsim device is set-up using NetworkManager,
because NetworkManager sends 0 as MAX values, as it is pointless to
retrieve them in extra call, because they should be read-only. Then,
the device is left in incosistent state (value > MAX).

Maxime points out that the polling code in mpc_i2c_isr should use the
_atomic API because it is called in an irq context and that the
behaviour of the MCF bit is that it is 1 when the byte transfer is
complete. All of this means the original code was effectively a
udelay(100).
Fix this by using readb_poll_timeout_atomic() and removing the negation
of the break condition.

In driver/md/md.c, if the function autorun_array() is called,
the problem of double free may occur.
In function autorun_array(), when the function do_md_run() returns an
error, the function do_md_stop() will be called.
The function do_md_run() called function md_run(), but in function
md_run(), the pointer mddev->private may be freed.
The function do_md_stop() called the function __md_stop(), but in
function __md_stop(), the pointer mddev->private also will be freed
without judging null.
At this time, the pointer mddev->private will be double free, so it
needs to be judged null or not.

erratum_set_next_event_generic()
With some specific kernel configuration and Clang, the kernel fails
to like with something like:
ld.lld: error: undefined symbol: __compiletime_assert_200
>>> referenced by arch_timer.h:156 (./arch/arm64/include/asm/arch_timer.h:156)

>>> clocksource/arm_arch_timer.o:(erratum_set_next_event_generic) in archive drivers/built-in.a
make: *** [Makefile:1161: vmlinux] Error 1
These are due to the BUILD_BUG() macros contained in the low-level
accessors (arch_timer_reg_{write,read}_cp15) being emitted, as the
access type wasn't known at compile time.
Fix this by making erratum_set_next_event_generic() __force_inline,
resulting in the 'access' parameter to be resolved at compile time,
similarly to what is already done for set_next_event().

The driver refuses to probe with -EINVAL since the commit 5d9814df0aec

Before the driver used to probe successfully if either "clock-freq" or

That commit changed
if (A && B)

Make xhci_disable_slot() synchronous, thus ensuring it, and
xhci_free_dev() calling it return after xHC controller completes
the disable slot command.
Otherwise the roothub and xHC host may runtime suspend, and clear the
command ring while the disable slot command is being processed.
This causes a command completion mismatch as the completion event can't
be mapped to the correct command.
Command ring gets out of sync and commands time out.
Driver finally assumes host is unresponsive and bails out.

When the xHCI is quirked with XHCI_RESET_ON_RESUME, runtime resume
routine also resets the controller.
This is bad for USB drivers without reset_resume callback, because
there's no subsequent call of usb_dev_complete() ->
usb_resume_complete() to force rebinding the driver to the device. For
instance, btusb device stops working after xHCI controller is runtime
resumed, if the controlled is quirked with XHCI_RESET_ON_RESUME.
So always take XHCI_RESET_ON_RESUME into account to solve the issue.

Adds drm support for the Unisoc's display subsystem.
This is drm kms driver, this driver provides support for the
application framework in Android, Yocto and more.
Application framework can access Unisoc's display internal
peripherals through libdrm or libkms, it's test ok by modetest
(DRM/KMS test tool) and Android HWComposer.
v4:
- Move the devm_drm_dev_alloc to master_ops->bind function.
- The managed drmm_mode_config_init() it is no longer necessary for drivers to explicitly call drm_mode_config_cleanup, so delete it.
v5:
- Remove subdir-ccflgas-y for Makefile.
- Keep the selects sorted by alphabet for Kconfig.

...and gpio-ranges
pinctrl-bcm2835 is a combined pinctrl/gpio driver. Currently the gpio
side is registered first, but this breaks gpio hogs (which are
configured during gpiochip_add_data). Part of the hog initialisation
is a call to pinctrl_gpio_request, and since the pinctrl driver hasn't
yet been registered this results in an -EPROBE_DEFER from which it can
never recover.
Change the initialisation sequence to register the pinctrl driver
first.
This also solves a similar problem with the gpio-ranges property, which
is required in order for released pins to be returned to inputs.
