From 5689b28890f4a7c4e12290dbf2c29a9d23047335 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Fri, 18 May 2012 09:31:18 -0300 Subject: [PATCH] [media] v4l: Unify selection targets across V4L2 and V4L2 subdev interfaces Change the users of V4L2_SUBDEV_SEL_TGT_* targets to use V4L2_SEL_TGT_* instead. The common definitions are moved to a new header file, include/linux/v4l2-common.h.
