From 24644035d52a9da2af319dd05b1a580a0a7069a0 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Sat, 3 May 2014 21:31:57 -0300 Subject: [PATCH] [media] smiapp: Return correct return value in smiapp_registered() Prepare for supporting systems using the Device tree. Should the resources not be available at the time of driver probe(), the EPROBE_DEFER error code must be also returned from its probe function.
