Subject: [PATCH 3.15 03/37] media: af9035: override tuner id when bad value set into eeprom
Date: Tue, 29 Jul 2014 18:48:39 -0700	[thread overview]
Message-ID: <20140730014827.760224199@linuxfoundation.org> (raw)
In-Reply-To: <20140730014827.565626091@linuxfoundation.org>

3.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Antti Palosaari <crope@iki.fi>

commit 1cbbf90d0406913ad4b44194b07f4f41bde84e54 upstream.

Tuner ID set into EEPROM is wrong in some cases, which causes driver
to select wrong tuner profile. That leads device non-working. Fix
issue by overriding known bad tuner IDs with suitable default value.

Thanks to MX-NET Telekomunikace s.r.o. for providing non-working
DTV stick, that I could fix the bug!
