USB-serial fixes for v4.4-rc3
Here are some device-id fixes that remove a HID device from cp210x, and
adds support for another Infineon flash-loader device. The flash-loader
device presents itself as a CDC-ACM device even though it is clearly
not, so we need to blacklist it in the cdc-acm driver as well.

usb: fixes for v4.4-rc3
Here's our second round of fixes. Some of the bugs are pretty old like
the one on pxa27x suspend implementation.
The most important part is a randbuild warning fix on MUSB CPPI DMA
engine by Arnd, a couple fixes by Felipe Tonello on f_midi (first one
makes sure we only transmit on enabled ep IN while second plugs a memory
leak) and a NULL pointer dereference fix on renesas usbhs.
Note that we also have a new compatible string being added for the MXS
PHY.

When switching between two clock sources using the FLL freerun to smooth
the transition we should wait 32uS after putting the FLL into freerun
before we proceed. In practice we appear to be getting enough delay from

When doing the initial setup both the hclk and the aclk need to be
enabled otherwise the board will simply hang. This only occurs when
building the vop driver as a module, when its built-in the initial setup
happens to run before the clock framework shuts of unused clocks
(including the aclk).
While there also switch to doing prepare and enable in one step rather
then separate steps to reduce the amount of code required.

There's currently two places where the gma500 fault handler relies
upon dev->struct_mutex:
- To protect r->mappping
- To make sure vm_insert_pfn isn't called concurrently (in which case
the 2nd thread would get an error code).
Everything else (specifically psb_gtt_pin) is already protected by
some other locks. Hence just create a new driver-private mmap_mutex
just for this function.
With this gma500 is complete dev->struct_mutex free!

This is init/teardown code, locking is just to appease locking checks.
And since gem create/free doesn't need this any more there's really no
reason for grabbing dev->struct_mutex.

It's either init code or already protected by other means. Note
that psb_gtt_pin/unpin has it's own lock, and that's really the
only piece of driver private state - all the modeset state is
protected with modeset locks already.
The only important bit is to switch all gem_obj_unref calls to the

We have relied upon the sole caller (wait_ioctl) validating the timeout
argument. However, when waiting for multiple requests I forgot to ensure
that the timeout was still positive on the later requests. This is more
simply done inside __i915_wait_request.

clock difference
Rather than using drm_match_cea_mode() to see if the EDID detailed
timings are supposed to represent one of the CEA/HDMI modes, add a
special version of that function that takes in an explicit clock
tolerance value (in kHz). When looking at the detailed timings specify
the tolerance as 5kHz due to the 10kHz clock resolution limit inherent
in detailed timings.
drm_match_cea_mode() uses the normal KHZ2PICOS() matching of clocks,
which only allows smaller errors for lower clocks (eg. for 25200 it
won't allow any error) and a bigger error for higher clocks (eg. for
297000 it actually matches 296913-297000). So it doesn't really match
what we want for the fixup. Using the explicit +-5kHz is much better
for this use case.
Not sure if we should change the normal mode matching to also use
something else besides KHZ2PICOS() since it allows a different
proportion of error depending on the clock. I believe VESA CVT
allows a maximum deviation of .5%, so using that for normal mode
matching might be a good idea?

Second set of IIO fixes for the 4.4 cycle.
Some of these were waiting for various code to hit during the merge
window - others have simply shown up recently.
* Dummy - fix a bug introduced recently that stops events actually
reaching userspace.
* Lidar - return -EINVAL on getting a report of an invalid reading from
the device. This could mean that nothing is in range, or something
else has gone wrong. Basically it tells us nothing useful beyond the
reading is bogus and should be ignored.
* apds9660 - make sure to call pm_runtime_mark_last_busy when reading

* core - fix up a few missues of the WARN macro.
* spmi-vadc - fix a missing of_node_put when breaking out of

The mpt2sas driver was recently folded into mpt3sas to reduce code
duplication.
To avoid problems for people that only have CONFIG_SCSI_MPT2SAS in their
.config we introduce a dummy option that will select MPT3SAS if MPT2SAS
was previously enabled.
This is a temporary measure and we will deprecate this config option in
4.6.

In order to check for overlapping reserved memory regions, we first need
to sort the array of memory regions. This is implemented using sort(),
and a custom comparison function __rmem_cmp().
Unfortunatley __rmem_cmp() doesn't work in all cases. Because the two
base values are phys_addr_t, they may be u64 on some platforms, in which
case subtracting one from the other and then (implicitly) casting to int
does not give us the -ve/0/+ve value we need.
This leads to incorrect reports about overlaps, eg:
ibm,slw-image@1ffe600000 (0x0000001ffe600000--0x0000001ffe700000) overlaps with
ibm,firmware-allocs-memory@1000000000 (0x0000001000000000--0x0000001000dc0200)
Fix it by just doing the standard double if and return 0 logic.

Pull tracing fixes from Steven Rostedt:
"I found two minor bugs while doing development on the ring buffer
code.
The first is something that's been there since its creation. If a
reader reads a page out of the ring buffer before there's any events
on it, it can get an out of date timestamp for that event. It may be
off by a few microseconds, more if the first event gets discarded.
The fix was to only update the reader time stamp when it actually sees
an event on the page, instead of just reading the timestamp from the
page even if it has no events on it. That timestamp is still volatile
until an event is present.
The second bug is more recent. Instead of passing around parameters a
descriptor was made and the parameters are passed via a single
descriptor. This simplified the code a bit. But there was one place
that expected the parameter to be passed by value not reference (which
a descriptor now does). And it added to the length of the event,
which may be ignored later, but the length should not have been
increased. The only real problem with this bug is that it may
allocate more than was needed for the event"

When support for _FIT was added, the code presumed that the data
returned by the _FIT method is identical to the NFIT table, which
starts with an acpi_table_header. However, the _FIT is defined
to return a data in the format of a series of NFIT type structure
entries and as a method, has an acpi_object header rather tahn
an acpi_table_header.
To address the differences, explicitly save the acpi_table_header
from the NFIT, since it is accessible through /sys, and change
the nfit pointer in the acpi_desc structure to point to the
table entries rather than the headers.

The size of NFIT tables don't necessarily match the size of the

no block control windows than for a device with block control windows.
Other tables, such as Flush Hint Address Structure and the Interleave

Account for the size difference when comparing table entries by
using the actual table size from the table header if it's less
than the structure size.

Hi,
For a brief moment I was tricked into thinking that:
In-kernel debugger (EXPERIMENTAL) (ACPI_DEBUGGER) [N/y/?] (NEW)
might be something useful. Better describe the feature to reduce
such confusion.

Because interrupt endpoints usually transmit such
small amounts of data, it seems pointless to prestart
transfers and try to get speed improvements. This
patch also sorts out a problem with CDC ECM function
where its notification endpoint gets stuck in busy
state and we continuously issue Update Transfer
commands.
Fixes: 8a1a9c9e4503 ("usb: dwc3: gadget: start transfer on XFER_COMPLETE")

Dmitry provided a syzkaller (http://github.com/google/syzkaller)
generated program that triggers the WARNING at
net/ipv4/tcp.c:1729 in tcp_recvmsg() :
WARN_ON(tp->copied_seq != tp->rcv_nxt &&
!(flags & (MSG_PEEK | MSG_TRUNC)));
His program is specifically attempting a Cross SYN TCP exchange,
that we support (for the pleasure of hackers ?), but it looks we
lack proper tcp->copied_seq initialization.
Thanks again Dmitry for your report and testings.

The gianfar driver has recently been enabled on arm64 but fails to build
since it check the return value of platform_get_irq() against NO_IRQ. Fix
this by instead checking for a negative error code.
Even on ARM where this code was previously being built this check was
incorrect since platform_get_irq() returns a negative error code which
may not be exactly the (unsigned int)(-1) that NO_IRQ is defined to be.

This driver can be built on arm64 but relies on NO_IRQ to check the return
value of irq_of_parse_and_map() which fails to build on arm64 because the
architecture does not provide a NO_IRQ. Fix this to correctly check the
return value of irq_of_parse_and_map().
Even on ARM systems where the driver was previously used the check was
broken since on ARM NO_IRQ is -1 but irq_of_parse_and_map() returns 0 on
error.

sendpage did not care about credentials at all. This could lead to
situations in which because of fd passing between processes we could
append data to skbs with different scm data. It is illegal to splice those
skbs together. Instead we have to allocate a new skb and if requested
fill out the scm details.
