From b74c0aac357e5c71ee6de98b9887fe478bc73cf4 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 29 Mar 2009 18:00:07 -0300 Subject: [PATCH] V4L/DVB (11366): v4l: remove obsolete header and source v4l2-subdev.c and v4l2-i2c-drv-legacy.h were used to support the old i2c API. All v4l drivers are now converted to v4l2_subdev, so these two files can be removed.
