Subject: [PATCH] [35/50] pvrusb2: fix g/s_tuner support

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Hans Verkuil <hans.verkuil@...co.com>

[ upstream commit 50e9efd60b213ce43ad6979bfc18e25eec2d8413 ]

The tuner-core subdev requires that the type field of v4l2_tuner is
filled in correctly. This is done in v4l2-ioctl.c, but pvrusb2 doesn't
use that yet, so we have to do it manually based on whether the current
input is radio or not.

Tested with my pvrusb2.
