From 20deebfe17b20ded00ba404adbcd014eb2b024c1 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Thu, 6 Sep 2012 10:07:25 -0300 Subject: [PATCH] [media] em28xx: fix tuner/frequency handling v4l2-compliance found problems with frequency clamping that wasn't reported correctly and missing tuner index checks. Also removed unnecessary tuner type checks (these are now done by the v4l2 core).
