media: ti: davinci: vpbe_display.c: return 0 instead of 'ret'.
Since 'ret' is known to be 0, just return '0'. This fixes a smatch warning: vpbe_display.c:1152 vpbe_display_open() warn: missing error code? 'err' Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Cc: "Lad, Prabhakar" <prabhakar.csengg@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
