Subject[PATCH 10/34] [media] DaVinci-VPBE: Check return value of a setup_if_config() call in vpbe_set_output()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 12 Oct 2016 09:56:56 +0200

* A function was called over the pointer "setup_if_config" in the data
structure "venc_platform_data". But the return value was not used so far.
Thus assign it to the local variable "ret" which will be checked with
the next statement.

Fixes: 9a7f95ad1c946efdd7a7a72df27db738260a0fd8 ("[media] davinci vpbe: add dm365 VPBE display driver changes")

* Pass a value to this function call without storing it in an intermediate
variable before.

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