Subject[PATCH 3.2 19/87] ALSA: fm801: propagate TUNER_ONLY bit when autodetected
3.2.77-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

commit dbec6719ac036f68568d8488805d41346c021eff upstream.

The commit d7ba858a7f7a (ALSA: fm801: implement TEA575x tuner autodetection)
brings autodetection to the driver. However the autodetection algorithm misses
the TUNER_ONLY bit if it is supplied by the user.

Thus, user gets weird messages and no card registered.

snd_fm801 0000:0d:01.0: detected TEA575x radio type SF64-PCR
snd_fm801 0000:0d:01.0: AC'97 interface is busy (1)
snd_fm801 0000:0d:01.0: AC'97 interface is busy (1)
...
snd_fm801 0000:0d:01.0: AC'97 0 does not respond - RESET
snd_fm801 0000:0d:01.0: AC'97 interface is busy (1)
snd_fm801 0000:0d:01.0: AC'97 interface is busy (1)
snd_fm801 0000:0d:01.0: AC'97 0 access is not valid [0x0], removing mixer.
snd_fm801: probe of 0000:0d:01.0 failed with error -5

Do a copy of TUNER_ONLY bit to be applied after autodetection is done.
