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.
