Pull staging driver updates from Greg KH:
"Here is the big set of staging driver updates for 5.18-rc1.
Loads of tiny cleanups for almost all staging drivers in here, nothing
major at all. Highlights include:
- remove the ashmem Android driver. It is long-dead and if there are
any legacy userspace applications still using it, the Android
kernel images will maintain it, the community shouldn't care about
it anymore
- wfx wifi driver major cleanups. Should be ready to merge out of
staging soon, and will coordinate with the wifi maintainers after
-rc1 is out
- major cleanups and unwinding of the layers of the r8188eu driver.
It's amazing just how many unneeded layers of abstraction is in
there, just when we think it's done, another is found...
- lots of tiny coding style cleanups in many other staging drivers.
All have been in linux-next for a while with no reported problems"

On devices with DMM, all allocations are done through either DMM or TILER.
DMM/TILER being a limited resource means that such allocations will start
to fail before actual free memory is exhausted. What is even worse is that
with time DMM/TILER space gets fragmented to the point that even if we have
enough free DMM/TILER space and free memory, allocation fails because there
is no big enough free block in DMM/TILER space.
Such failures can be easily observed with OMAP xorg DDX, for example -
starting few GUI applications (so buffers for their windows are allocated)
and then rotating landscape<->portrait while closing and opening new
windows soon results in allocation failures.
Fix that by mapping buffers through DMM/TILER only when really needed,
like, for scanout buffers.

Currently code allocates non-scanout BOs from SHMEM and those objects are
accessible to userspace by mmap(). However, on devices with no DMM (like
OMAP3), the same objects are not accessible by kernel drivers that want to
render to them as code refuses to export them. In turn this means that on
devices with no DMM, all buffers must be allocated as scanout, otherwise
only CPU can access them. On those devices, scanout buffers are allocated
from CMA, making those allocations highly unreliable.
Fix that by implementing functionality to export SHMEM backed buffers on
devices with no DMM. This makes CMA memory only being used when needed,
instead for every buffer that has to be off-CPU rendered.

cleanup the s390's use of the timer API
- del_timer() contains timer_pending() condition
- mod_timer(timer, expires) is equivalent to:
del_timer(timer);
timer->expires = expires;
add_timer(timer);
If the timer is inactive it will be activated, using add_timer() on
condition !timer_pending(&private->timer) is redundant.
Just cleanup, no logic change.

While the original code is valid, it is not the obvious choice for the
sizeof() call and in preparation to limit the scope of the list iterator
variable the sizeof should be changed to the size of the variable
being allocated.

The vfio_ap device driver registers a group notifier function to handle
the VFIO_GROUP_NOTIFY_SET_KVM event signalling the KVM pointer has been
set or cleared. There are two helper functions invoked by the handler
function: One called when the KVM pointer has been set, and the other
when the pointer is cleared.
The kernel doc for both of these functions contains a comment introduced
by commit 0cc00c8d4050 (s390/vfio-ap: fix circular lockdep when
setting/clearing crypto masks) that is no longer valid. This patch removes
this comment from the kernel doc of each helper function.
Commit 86956e70761b (s390/vfio-ap: replace open coded locks for
VFIO_GROUP_NOTIFY_SET_KVM notification) added a parameter to the signature
of the helper function that handles the event indicating the KVM pointer
has been cleared. The parameter added was the KVM pointer itself.
One of the function's primary purposes is to clear the KVM pointer from the
ap_matrix_mdev instance in which it is stored. Since the callers of this
function derive the KVM pointer passed to the function from the
ap_matrix_mdev object itself, it is completely unnecessary to include this
parameter in the function's signature since it can simply be retrieved from
the ap_matrix_mdev object which is also passed in. This patch removes the
KVM pointer from the function's signature.

The driver currently uses a CPU family match of 17h to determine
EFCH_PM_DECODEEN_WDT_TMREN register support. This family check will not
support future AMD CPUs and instead will require driver updates to add
support.
Remove the family 17h family check and add a check for SMBus PCI
revision ID 0x51 or greater. The MMIO access method has been available
since at least SMBus controllers using PCI revision 0x51. This revision
check will support family 17h and future AMD processors including EFCH
functionality without requiring driver changes.

Combine MMIO base address and alternate base address detection. Combine
based on layout type. This will simplify the function by eliminating
a switch case.
Move existing request/release code into functions. This currently only
supports port I/O request/release. The move into a separate function
will make it ready for adding MMIO region support.

Commit e07a4c79ca75 ("watchdog: orion_wdt: use timer1 as a pretimeout")
added support for a pretimeout on Armada-38x variants. Because the
Armada-XP variants use armada370_start/armada370_stop (due to missing an
explicit RSTOUT mask bit for the watchdog). Add the required pretimeout
support to armada370_start/armada370_stop for Armada-XP.

Add support for not stopping the watchdog
when the userspace application quits. At
closing of the device, the driver cannot
determine if this was a graceful closure
or if the app crashed. If the support
of nowayout on this driver, the system integrator
can select the behaviour by setting the kernel
config and enabling it.
