Darshana Patil acc83ca211 video: driver: request api changes for dynamic controls
- Request api allows to synchronize controls along
  with buffers.
- Client allocates a request fd. This request fd is
  associated with control and set using s_ext_ctrls.
  Such controls are stored by the framework and not
  applied immediately.
- Request fd is also associated with input qbuf and
  queued to driver. Following this actual request is
  queued. Buffers do not enter the queue untill the
  request is queued.
- As part of qbuf, driver call request_setup() which
  inturn sets the control to driver.
