Subject: V4L/DVB:  si470x: -EINVAL overwritten in si470x_vidioc_s_tuner()
Author:  Tobias Lorenz <[email protected]>
Date:    Sat Jul 10 13:01:33 2010 -0300

This patch to the si470x_vidioc_s_tuner function was developed in
cooperation with Roel Kluin <[email protected]>. It sets the default
retval to 0 instead of -EINVAL, identical to what is done in all other
set/get functions of v4l2_ioctl_ops. This is just as cosmetic change, as
retval is directly overwritten by the si470x_disconnect_check() anyway.
