[PATCH 3/3] [media] hdpvr: Return an error code only as a constant in hdpvr_alloc_buffers()

Show all headers | View raw

From: Markus Elfring <elfring@users.sourceforge.net>

* Return an error code without storing it in an intermediate variable.

* Delete the local variable "retval" which became unnecessary
  with this refactoring.
