From 6b1446bc7c89025e07037f9c238a60b6fbe3c207 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sun, 28 Feb 2016 23:28:38 -0300 Subject: [PATCH] [media] v4l: vsp1: video: Fix coding style Commit 54b5a749b4f3 ("[media] v4l: vsp1: Use media entity enumeration interface") wasn't aligned with the driver coding style. Fix it by renaming the rval variable to ret. Furthermore shorten lines by accessing the media_device instance in a more straightforward fashion.
