From 823329dfee7224712569cc4899720bc470a2fe56 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sun, 15 Nov 2015 19:42:01 -0200 Subject: [PATCH] [media] v4l: vsp1: Move subdev initialization code to vsp1_entity_init() Don't duplicate the code in every module driver, centralize it in a single place.
