Linus Torvalds 23908db413 Staging driver patches for 4.2-rc1
Here's the big, really big, staging tree patches for 4.2-rc1.
 
 Loads of stuff in here, almost all just coding style fixes / churn, and
 a few new drivers as well, one of which I just disabled from the build a
 few minutes ago due to way too many build warnings.
 
 Other than the one "disable this driver" patch, all of these have been
 in linux-next for quite a while with no reported issues.

Ksenija Stanojevic 3466835061 [media] Staging: media: lirc: Replace timeval with ktime_t
'struct timeval last_tv' is used to get the time of last signal change
and 'struct timeval last_intr_tv' is used to get the time of last UART
interrupt.
32-bit systems using 'struct timeval' will break in the year 2038, so we
have to replace that code with more appropriate types.
Here struct timeval is replaced with ktime_t.

Mauro Carvalho Chehab 0df289a209 [media] dvb: Get rid of typedev usage for enums
The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.

So, let's do it.

This patch was generated by this shell script:

	for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

While here, make CodingStyle fixes on the affected lines.

Mauro Carvalho Chehab af8a819a25 [media] lirc_imon: simplify error handling code
Instead of using a state machine and a switch with lots of
fall-trough, use gotos and cleanup the error handling loop.

That removes those two smatch warnings:
	drivers/staging/media/lirc/lirc_imon.c:933 imon_probe() warn: possible memory leak of 'context'
	drivers/staging/media/lirc/lirc_imon.c:933 imon_probe() warn: possible memory leak of 'driver'

And make the error handling code more standard.

When mapping from a V4L2 pixel format to a media bus format in the
VIDIOC_TRY_FMT and VIDIOC_S_FMT handlers, the requested format may be
unsupported by the driver. Return a hardcoded default format instead of
WARN()ing in that case.

Markus Elfring bf104c238d [media] mn88472: One function call less in mn88472_init() after error detection
The release_firmware() function was called in three cases by the mn88472_init()
function during error handling even if the passed variable "fw" contained still
a null pointer.

This implementation detail could be improved by the introduction of another
jump label.

Markus Elfring 68feaa6b8b [media] mn88472: Deletion of an unnecessary check before the function call "release_firmware"
The release_firmware() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

Hans Verkuil f7234138f1 [media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_config
If a subdevice pad op is called from a bridge driver, then there is
no v4l2_subdev_fh struct that can be passed to the subdevice. This
made it hard to use such subdevs from a bridge driver.

This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config
pointer in the pad ops. This allows bridge drivers to use the various
try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it
along to the pad op.

The v4l2_subdev_get_try_* macros had to be changed because of this, so
I also took the opportunity to use the full name of the v4l2_subdev_get_try_*
functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do
'git grep v4l2_subdev_get_try_format' you will actually find the header
where it is defined.

One remark regarding the drivers/staging/media/davinci_vpfe patches: the
*_init_formats() functions assumed that fh could be NULL. However, that's
not true for this driver, it's always set. This is almost certainly a copy
and paste from the omap3isp driver. I've updated the code to reflect the
fact that fh is never NULL.
