From 9ff889b612ae3c36a537b8f023dd0201412de87f Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 17 May 2013 07:31:04 -0300 Subject: [PATCH] [media] v4l: of: Return an int in v4l2_of_parse_endpoint() When CONFIG_OF is not defined the v4l2_of_parse_endpoint() function is defined as a stub that returns -ENOSYS. Make the real function return an integer as well to be able to differentiate between the two cases.
