[ Upstream commit df9166bfa7 ]
This patch reworks the fdmi symbolic node name data for the following two
issues:
- Correcting extraneous periods following the DV and HN fdmi data fields.
- Avoiding buffer overflow issues when formatting the data.
The fix to the fist issue is to just remove the characters.
The fix to the second issue has all data being staged in temporary storage
before being moved to the real buffer.

The driver currently handles vblank events only when updating planes on

In UFS host reset and restore path, before probe, we stop and start the
host controller once. After host controller is stopped, the pending
requests, if any, are cleared from the doorbell, but no completion IRQ
would be raised due to the hba is stopped. These pending requests shall be
completed along with the first NOP_OUT command (as it is the first command
which can raise a transfer completion IRQ) sent during probe. Since the
OCSs of these pending requests are not SUCCESS (because they are not yet
literally finished), their UPIUs shall be dumped. When there are multiple
pending requests, the UPIU dump can be overwhelming and may lead to
stability issues because it is in atomic context. Therefore, before probe,
complete these pending requests right after host controller is stopped and
silence the UPIU dump from them.

ACPICA commit 29cc8dbc5463a93625bed87d7550a8bed8913bf4
create_buffer_field is a deferred op that is typically processed in
load pass 2. However, disassembly of control method contents walk the
parse tree with ACPI_PARSE_LOAD_PASS1 and AML_CREATE operators are
processed in a later walk. This is a problem when there is a control
method that has the same name as the AML_CREATE object. In this case,
any use of the name segment will be detected as a method call rather
than a reference to a buffer field. If this is detected as a method
call, it can result in a mal-formed parse tree if the control methods
have parameters.
This change in processing AML_CREATE ops earlier solves this issue by
inserting the named object in the ACPI namespace so that references
to this name would be detected as a name string rather than a method
call.

1 warning generated.
This warning happens because the shift operation is implicitly converted
to a boolean in v4l2_device_mask_call_all before being negated. This can
be solved by just comparing the mask result to 0 explicitly so that
there is no boolean conversion. The ultimate goal is to enable
-Wtautological-compare globally because there are several subwarnings
that would be helpful to have.
For visual consistency and avoidance of these warnings in the future,
all of the implicitly boolean conversions in the v4l2_device macros
are converted to explicit ones as well.

Allow greater variance in a run and retry to further reduce flakiness.
Observed errors are one of two kinds: either the packet arrives too
early or late at recv(), or it was dropped in the qdisc itself and the
recv() call times out.
In the latter case, the qdisc queues a notification to the error
queue of the send socket. Also explicitly report this cause.

During suspend, a transition to D3cold is attempted, however the affected
platforms do not seem to cut the power to the PCI device when in this
state, so the device stays in D3hot.
Upon resume, the D3hot-to-D0 transition is successful only if the D3 delay
is increased to 20ms. The transition failure does not appear to be
detectable as a CRS condition. Add a PCI quirk to increase the delay on the
affected hardware.

The AVerMedia CE310B is a simple composite + S-Video + stereo audio
capture card, and uses only the CX23888 to perform all of these
functions.
I've tested both video inputs and the audio interface and confirmed that
they're all working. However, there are some issues:
* Sometimes when I switch inputs the video signal turns black and can't
be recovered until the system is rebooted. I haven't been able to
determine the cause of this behavior, nor have I found a solution to
fix it or any workarounds other than rebooting.
* The card sometimes seems to have trouble syncing to the video signal,
and some of the VBI data appears as noise at the top of the frame, but
I assume that to be a result of my very noisy RF environment and the
card's unshielded input traces rather than a configuration issue.

Previously quirk_paxc_bridge() was applied when the iproc driver was

This happened because it was under #ifdef CONFIG_PCIE_IPROC_PLATFORM:
PCIE_IPROC_PLATFORM=y causes CONFIG_PCIE_IPROC_PLATFORM to be defined, but
PCIE_IPROC_PLATFORM=m causes CONFIG_PCIE_IPROC_PLATFORM_MODULE to be

Move quirk_paxc_bridge() to pcie-iproc.c and drop the #ifdef so the quirk
is always applied, whether iproc is built-in or a module.

Fix by introducing a second padata CPU hotplug state before

Convert cpu_to_le16(le16_to_cpu(frame->datalen) + len) to
use le16_add_cpu(), which is more concise and does the same thing.

Qiang Zhao points out that these offsets get written to 16-bit
registers, and there are some QE platforms with more than 64K
muram. So it is possible that qe_muram_alloc() gives us an allocation
that can't actually be used by the hardware, so detect and reject
that.

[ Upstream commit b8a039d377 ]
RK808 can leverage a couple of GPIOs to tweak the ramp rate during DVS
(Dynamic Voltage Scaling). These GPIOs are entirely optional but a
dev_warn() appeared when cleaning this driver to use a more up-to-date
gpiod API. At least reduce the log level to 'info' as it is totally
fine to not populate these GPIO on a hardware design.
This change is trivial but it is worth not polluting the logs during
bringup phase by having real warnings and errors sorted out
correctly.
