From 320c63870941ef3bb6e08e979d894ad6d51340d7 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Sun, 16 Mar 2014 18:13:05 -0300 Subject: [PATCH] [media] e4000: make VIDEO_V4L2 dependency optional That tuner driver is mainly for DVB API, but there is some V4L2 API controls for SDR usage. Make driver compile conditional so that V4L2 is not mandatory. Without the V4L2 support driver is build as a DVB only, without SDR controls. Fixes following errors reported by kbuild test robot: ERROR: "v4l2_ctrl_auto_cluster" [drivers/media/tuners/e4000.ko] undefined! ERROR: "v4l2_ctrl_new_std" [drivers/media/tuners/e4000.ko] undefined!
