vfs: do bulk POLL* -> EPOLL* replacement

2018-02-11T22:34:03+00:00

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/^\([^\"]*\)\(\\)/\\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.

Merge tag 'media/v4.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

2018-02-06T19:27:48+00:00

Pull media updates from Mauro Carvalho Chehab:

 - videobuf2 was moved to a media/common dir, as it is now used by the
   DVB subsystem too

 - Digital TV core memory mapped support interface

 - new sensor driver: ov7740

 - several improvements at ddbridge driver

 - new V4L2 driver: IPU3 CIO2 CSI-2 receiver unit, found on some Intel
   SoCs

 - new tuner driver: tda18250

 - finally got rid of all LIRC staging drivers

 - as we don't have old lirc drivers anymore, restruct the lirc device
   code

 - add support for UVC metadata

 - add a new staging driver for NVIDIA Tegra Video Decoder Engine

 - DVB kAPI headers moved to include/media

 - synchronize the kAPI and uAPI for the DVB subsystem, removing the gap
   for non-legacy APIs

 - reduce the kAPI gap for V4L2

 - lots of other driver enhancements, cleanups, etc.

media: entity: Add a nop variant of media_entity_cleanup

2018-01-23T13:12:01+00:00

Add nop variant of media_entity_cleanup. This allows calling
media_entity_cleanup whether or not Media controller is enabled,
simplifying driver code.

Also drop #ifdefs on a few drivers around media_entity_cleanup().

media: v4l2-async: better describe match union at async match struct

2017-12-29T12:15:14+00:00

Now that kernel-doc handles nested unions, better document the
match union at struct v4l2_async_subdev.

media: v4l2-async: simplify v4l2_async_subdev structure

2017-12-29T12:14:28+00:00

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.
