69d468f477 drm/nouveau/priv: punt messages to debug level
Ideally we'd be able to keep these at a more obvious error level, as
they're a good indication of us doing something wrong.

However, NVIDIA's FECS/GPCCS firmware touches registers that trigger
priv ring faults, and we can't do anything to fix that ourselves due
to the need for them to be signed by NVIDIA.

This issue was reported a while back, but hasn't been fixed, so, for
now we will hide the messages to prevent spamming Optimus users with
messages whenever the NVIDIA GPU is powered off and on again.

b5a8ffad0e arm64: dts: r8a7795: Tidyup Audio-DMAC channel for DVC
Current	Audio-DMAC is assigned "rx" as Audio-DMAC0, "tx" as Audio-DMAC1.
Thus, DVC "tx" should be assigned as Audio-DMAC1, instead of Audio-DMAC0.

Because of this, current platform board (using SRC/DVC/SSI)
Playback/Capture both will use same Audio-DMAC0
(but it depends on audio data path).

First note is that this "rx" and "tx" are from each IP point,
it doesn't mean Playback/Capture.
Second note is that Audio DMAC assigned on DT is only for
Audio-DMAC, Audio-DMAC-peri-peri has no entry.

=> Audio-DMAC
-> Audio-DMAC-peri-peri
-- HW connection

>From PSCI v1.0, Suspend-to-RAM is supported via SYSTEM_SUSPEND PSCI

since necessary callback functions will be registered after a query
to ARM Trusted Firmware about SYSTEM_SUSPEND support.

861078381b drm: qxl: Don't alloc fbdev if emulation is not supported
If fbdev emulation is disabled, the QXL shutdown path will try to clean
a framebuffer that wasn't initialized, hitting the Oops below.  The
problem is that even when FBDEV_EMULATION is disabled we allocate the
qfbdev strutucture, but we don't initialize it.  The fix is to stop
allocating the memory, since it won't be used.  This allows the existing
verification in the cleanup hook to do it's job preventing the oops.

Now that we don't allocate the unused fbdev structure, we need to be
careful when dereferencing it in the PM suspend hook.

96418b5e2c scsi: lpfc: Fix eh_deadline setting for sli3 adapters.
A previous change unilaterally removed the hba reset entry point
from the sli3 host template. This was done to allow tape devices
being used for back up from being removed. Why was this done ?
When there was non-responding device on the fabric, the error
escalation policy would escalate to the reset handler. When the
reset handler was called, it would reset the adapter, dropping
link, thus logging out and terminating all i/o's - on any target.
If there was a tape device on the same adapter that wasn't in
error, it would kill the tape i/o's, effectively killing the
tape device state.  With the reset point removed, the adapter
reset avoided the fabric logout, allowing the other devices to
continue to operate unaffected. A hack - yes. Hint: we really
need a transport I_T nexus reset callback added to the eh process
(in between the SCSI target reset and hba reset points), so a
fc logout could occur to the one bad target only and stop the error
escalation process.

This patch commonizes the approach so it can be used for sli3 and sli4
adapters, but mandates the admin, via module parameter, specifically
identify which adapters the resets are to be removed for. Additionally,
bus_reset, which sends Target Reset TMFs to all targets, is also removed
from the template as it too has the same effect as the adapter reset.
