It's always compiled when any sound support is enabled although it's necessary only when OSS (the actual one or emulation) is enabled. This is slightly wasteful and as device redirection always registers character device region for major 14, it prevents alternative implementation. This patch introduces a new config SOUND_OSS_CORE which is selected iff OSS support is actually necessary and build the OSS core part conditionally. If OSS is disabled, soundcore merely contains sound_class but leaving it that way seems to be the simplest approach as otherwise sound_class should be in ALSA core file if OSS is disabled but should be in soundcore if OSS is enabled. Also, there's also the user confusion factor. Signed-off-by: Tejun Heo Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela --- Reading git-diff-tree failed
