[RFC: 2.6 patch] remove saa7134-oss

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The saa7134-oss is deprecated for quite some time, it's the only 
remaining OSS user outside of sound/oss/, and considering how few and 
what kind of soundcards are left supported by OSS I hardly see any use 
cases left.
