[RFC PATCH v2 0/4] staging: vt6655: Implement allocation failure handling

[Nam Cao <namcaov@gmail.com>]

This driver does not handle allocation failure when receiving data very
well. This patchset implements better handling in the case of allocation
failure.

Also do some necessary clean-up to implement this.

v2:
  - squash 3 commits that were doing a single thing
  - add new commit which removes a redundant assignment
  - take device_init_rx_desc() out of unnecessary else condition.
  - remove return statement at the end of void function
  - add a missing rd = rd->next statement in device_rx_srv(): because
    we already drop the current buffer, we should move on to the next
    buffer in the ring where new data will be written to.
