[media] media: davinci_vpfe: fix missing unlock on error in vpfe_prepare_pipeline()

2016-02-10T11:27:09+00:00

Add the missing unlock before return from function
vpfe_prepare_pipeline() in the error handling case.

video->lock is lock/unlock in function vpfe_open(),
and no need to unlock it here, so remove unlock
video->lock.

Pull second batch of media updates from Mauro Carvalho Chehab:
 "This is the second part of the media patches.  It contains the media
  controller next generation patches, with is the result of one year of
  discussions and development.  It also contains patches to enable media
  controller support at the DVB subsystem.

  The goal is to improve the media controller to allow proper support
  for other types of Video4Linux devices (radio and TV ones) and to
  extend the media controller functionality to allow it to be used by
  other subsystems like DVB, ALSA and IIO.

  In order to use the new functionality, a new ioctl is needed
  (MEDIA_IOC_G_TOPOLOGY).  As we're still discussing how to pack the
  struct fields of this ioctl in order to avoid compat32 issues, I
  decided to add a patch at the end of this series commenting out the
  new ioctl, in order to postpone the addition of the new ioctl to the
  next Kernel version (4.6).

  With that, no userspace visible changes should happen at the media
  controller API, as the existing ioctls are untouched.  Yet, it helps
  DVB, ALSA and IIO developers to develop and test the patches adding
  media controller support there, as the core will contain all required
  internal changes to allow adding support for devices that belong to
  those subsystems"

[media] staging: omap4iss: remove pads prefix from *_create_pads_links()

2016-01-11T14:19:08+00:00

The functions that create ISS internal and external entities links are
called *_create_pads_links() but the "pads" prefix is redundant since
the driver doesn't handle any other kind of link so it can be removed.

[media] media framework: rename pads init function to media_entity_pads_init()

2016-01-11T14:19:03+00:00

With the MC next gen rework, what's left for media_entity_init()
is to just initialize the PADs. However, certain devices, like
a FLASH led/light doesn't have any input or output PAD.

So, there's no reason why calling media_entity_init() would be
mandatory. Also, despite its name, what this function actually
does is to initialize the PADs data. So, rename it to
media_entity_pads_init() in order to reflect that.

The media entity actual init happens during entity register,
at media_device_register_entity(). We should move init of
num_links and num_backlinks to it.
