While checking the opportunity to add a display_gen
check to allow glk and cnl to be on same bucket I noticed
these FIXME cases here.
So I got the confirmation from HW architect that we actually
never needed this workaround.
"GLK supports 2 pixel per clock, so pixel clock can be up to 2 * cdclk."
So, this reverts commit 97f55ca5b662 ("drm/i915/glk: limit pixel
clock to 99% of cdclk workaround")

The 16Gb DIMM w/a is not applicable to BXT or GLK. Limit it to
the appropriate platforms.
This was especially harsh on GLK since we don't even try to read
the DIMM information on that platforms, hence valid_dimm was
always false and thus we always tried to apply the w/a.
Furthermore the w/a pushed the level 0 latency above the
level 1 latency, which doesn't really make sense.

asus_wmi_evaluate_method() is an empty dummy function when CONFIG_ASUS_WMI

Patch ad608fbcf166 changed how events were subscribed to address an issue
elsewhere. As a side effect of that change, the "add" callback was called
before the event subscription was added to the list of subscribed events,
causing the first event queued by the add callback (and possibly other
events arriving soon afterwards) to be lost.
Fix this by adding the subscription to the list before calling the "add"
callback, and clean up afterwards if that fails.

During the configuration phase of a CEC adapter it is trying to claim a

However, the code doesn't check if there were errors other than OK or NACK,

We get a headers_check warning about the newly defined ioctl command
structures:
./usr/include/linux/v4l2-controls.h:1105: found __[us]{8,16,32,64} type without #include <linux/types.h>
This is resolved by including linux/types.h, as suggested by the
warning, but there is another problem: Three of the four structures
have an odd number of __u8 headers, but are aligned to 32 bit in the
v4l2_ctrl_mpeg2_slice_params, so we get an implicit padding byte
for each one. To solve that, let's add explicit padding that can
be set to zero and verified in the kernel.

Current check for the last extra TRB for zero and unaligned transfers
does not account for isoc OUT. The last TRB of the Buffer Descriptor for
isoc OUT transfers will be retired with HWO=0. As a result, we won't
return early. The req->remaining will be updated to include the BUFSIZ
count of the extra TRB, and the actual number of transferred bytes
calculation will be wrong.
To fix this, check whether it's a short or zero packet and the last TRB
chain bit to return early.

Reading throught the new driver, I noticed that this cannot work on
big-endian CPUs, and the old DAC960 had exactly the same behavior.
To document this for the future, add a Kconfig dependency that prevents it
from being included in big-endian kernels. Since the hardware is really
old and we never had a working driver on it for big-endian platforms,
it's unlikely to make a difference to users.

I have not checked whether there are appropriate range checks before the

We return 0 unconditionally in 'cqspi_direct_read_execute()'.
However, 'ret' is set to some error codes in several error handling
paths.
Return 'ret' instead to propagate the error code.

The commit 37a3a98ef601 ("ALSA: hda - Enable runtime PM only for
discrete GPU") added a new ops gpu_bound to be called when GPU gets
bound. The patch overlooked, however, that vga_switcheroo_enable() is
called only once at GPU is bound. When an audio client is registered
after that point, it would miss the gpu_bound call. This leads to the
unexpected lack of runtime PM in HD-audio side.
For addressing that regression, just call gpu_bound callback manually
at vga_switcheroo_register_audio_client() when the GPU was already
bound.

If a bias is enabled on a pin of an Amlogic SoC, calling .pin_config_set()
with PIN_CONFIG_BIAS_DISABLE will not disable the bias. Instead it will
force a pull-down bias on the pin.
Instead of the pull type register bank, the driver should access the pull
enable register bank.

I noticed during the creation of another bugfix that the BCH_CONST_PARAMS
option that is set by DOCG3 breaks setting variable parameters for any
other users of the BCH library code.
The only other user we have today is the MTD_NAND software BCH
implementation (most flash controllers use hardware BCH these days
and are not affected). I considered removing BCH_CONST_PARAMS entirely
because of the inherent conflict, but according to the description in
lib/bch.c there is a significant performance benefit in keeping it.
To avoid the immediate problem of the conflict between MTD_NAND_BCH
and DOCG3, this only sets the constant parameters if MTD_NAND_BCH
is disabled, which should fix the problem for all cases that
are affected. This should also work for all stable kernels.
Note that there is only one machine that actually seems to use the
DOCG3 driver (arch/arm/mach-pxa/mioa701.c), so most users should have
the driver disabled, but it almost certainly shows up if we wanted
to test random kernels on machines that use software BCH in MTD.

This reverts commit 0586feba322e1de05075700eb4b835c8b683e62b
This patch makes it to need get_vblank_counter callback in crtc
to get frame counter from decon driver.
However, drm_dev->max_vblank_count is a member unique to
vendor's DRM driver but in case of ARM DRM, some CRTC devices
don't provide the frame counter value. As a result, this patch
made extension and clone mode not working.
Instead of this patch, we may need separated max_vblank_count
which belongs to each CRTC device, or need to implement frame
counter emulation for them who don't support HW frame counter.

Commit 4d2c0cda07448ea6980f00102dc3964eb25e241c set slave->link to
BOND_LINK_DOWN for 802.3ad bonds whenever invalid speed/duplex values
were read, to fix a problem with slaves getting into weird states, but
in the process, broke tracking of link failures, as going straight to
BOND_LINK_DOWN when a link is indeed down (cable pulled, switch rebooted)
means we broke out of bond_miimon_inspect()'s BOND_LINK_DOWN case because
!link_state was already true, we never incremented commit, and never got
a chance to call bond_miimon_commit(), where slave->link_failure_count
would be incremented. I believe the simple fix here is to mark the slave
as BOND_LINK_FAIL, and let bond_miimon_inspect() transition the link from
_FAIL to either _UP or _DOWN, and in the latter case, we now get proper
incrementing of link_failure_count again.
