This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.

If the framebuffer is enabled and error injection is disabled, then
creating the controls for the video output device would fail with an
error.

This is because the Clear Framebuffer control uses the 'vivid control
class' and that control class isn't added if error injection is disabled.

In addition, this control was added to e.g. vbi devices as well, which
makes no sense.

Move this control to its own control handler and handle it correctly.

The V4L2_ASYNC_MATCH_FWNODE match criteria requires just one
struct to be filled (struct fwnode_handle). The V4L2_ASYNC_MATCH_DEVNAME
match criteria requires just a device name.

So, it doesn't make sense to enclose those into structs,
as the criteria can go directly into the union.

That makes easier to document it, as we don't need to document
weird senseless structs.

At drivers, this makes even clearer about the match criteria.

Two orthogonal changesets caused a breakage at a printk
inside davinci. Commit a2d17962
("[media] davinci: Switch from V4L2 OF to V4L2 fwnode")
made davinci to use struct fwnode_handle instead of
struct device_node. Commit 68d9c47b
("media: Convert to using %pOF instead of full_name")
changed the printk to not use ->full_name, but, instead,
to rely on %pOF.

With both patches applied, the Kernel will do the wrong
thing, as warned by smatch:
	drivers/media/platform/davinci/vpif_capture.c:1399 vpif_async_bound() error: '%pOF' expects argument of type 'struct device_node*', argument 5 has type 'void*'

So, change the logic to actually print the device name
that was obtained before the print logic.

Driver calls request_firmware() whenever the device is opened for the
first time. As the device gets opened and closed, dev->num_inst == 1
is true several times. This is not necessary since the firmware is saved
in the fw_buf. s5p_mfc_load_firmware() copies the buffer returned by
the request_firmware() to dev->fw_buf.

fw_buf sticks around until it gets released from s5p_mfc_remove(), hence
there is no need to keep requesting firmware and copying it to fw_buf.

This might have been overlooked when changes are made to free fw_buf from
the device release interface s5p_mfc_release().

Fix s5p_mfc_load_firmware() to call request_firmware() once and keep state.
Change _probe() to load firmware once fw_buf has been allocated.

s5p_mfc_open() and it continues to call s5p_mfc_load_firmware() and init
hardware which is the step where firmware is written to the device.

This addresses the mfc_mutex contention due to repeated request_firmware()
calls from open() in the following circular locking warning:

When iterating through all endpoints using of_graph_get_next_endpoint(),
the refcount of the returned endpoint node is incremented and the refcount
of the node which is passed as previous endpoint is decremented.

So the caller doesn't need to call of_node_put() for each iterated node
except for error exit paths.  Otherwise we get "OF: ERROR: Bad

While here, use while(1) instead of for(; ;), as while is
the preferred syntax for such kind of loops.

timespec is generally deprecated because of the y2038 overflow.
In vivid, the usage is fine, since we are dealing with monotonic
timestamps, but we can also simplify the code by going to ktime_t.

Using ktime_divns() should be roughly as efficient as the old code,
since the constant 64-bit division gets turned into a multiplication
on modern platforms, and we save multiple 32-bit divisions that can be
expensive e.g. on ARMv7.

Deblocking filter allows to reduce blocking artifacts and improve
visual quality. This is configurable via the V4L2 API but eventually
not applied to the encoder.

Note that alpha and beta deblocking values are 32-bit signed (-6;+6).
