Subject: V4L/DVB (11364): tuner: remove i2c legacy code.
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=75b4c260fa93d99979a8b5bec5a621daff469398;p=linux-2.6-omap-h63xx.git

V4L/DVB (11364): tuner: remove i2c legacy code.

All drivers that use the tuner module now use v4l2_subdev, so we can remove the
legacy code from this module.

Note that TUNER_SET_CONFIG is still called by tuner-simple.c, so we have
to handle it via a .command callback. There must be a better way to do this,
but for now this will work.
