[media] c8sectpfe: fix return of garbage

2015-10-22T17:48:24+00:00

The variable err was never initialized, that means we had been checking
a garbage value in the for loop. Moreover if the segment is not outside
the firmware file then also we have been returning the garbage.
Initialize it to 0 so that on success we return the value and no need to
check in the for loop also as it is initially 0 and whenever that value
changes we have done a break from the loop.

[media] c8sectpfe: fix ininitialized error return on firmware load failure

2015-10-22T17:48:23+00:00

static analysis with cppcheck detected the following error:

[drivers/media/platform/sti/c8sectpfe/c8sectpfe-core.c:1210]:
  (error) Uninitialized variable: ret

ret is never initialised, so garbage is being returned. Instead
return the error return from the call of request_firmware_nowait

[media] c8sectpfe: Remove select on CONFIG_FW_LOADER_USER_HELPER_FALLBACK

2015-10-20T18:02:41+00:00

c8sectpfe driver selects CONFIG_FW_LOADER_USER_HELPER_FALLBACK by some
reason, but this option is known to be harmful, leading to minutes of
stalls at boot time.  The option was intended for only compatibility
for an old exotic system that mandates the udev interaction, and not a
thing a driver selects by itself.  Let's remove it.

[media] media/vivid-osd: fix info leak in ioctl

2015-10-20T17:34:29+00:00

The vivid_fb_ioctl() code fails to initialize the 16 _reserved bytes of
struct fb_vblank after the ->hcount member. Add an explicit
memset(0) before filling the structure to avoid the info leak.

[media] s5p-mfc: use MFC_BUF_FLAG_EOS to identify last buffers in decoder capture queue

2015-10-20T16:40:16+00:00

MFC driver never delivered EOS event to apps feeding constantly its capture
buffer with fresh buffers. The patch fixes it by marking last buffers
returned by MFC with MFC_BUF_FLAG_EOS flag and firing EOS event on
de-queuing such buffers.

[media] vivid: Add an option to configure the maximum number of devices

2015-10-03T14:36:24+00:00

The vivid driver currently has a hard-coded limit of 64 devices,
however there's nothing that prevents the creation of even more devices.
This commit adds a new driver option (which defaults to 64) to
allow this maximum number to be configurable.
