    sound: make OSS sound core optional · d886e87c
    Tejun Heo authored
    sound/sound_core.c implements soundcore.ko and contains two parts -
    sound_class which is shared by both ALSA and OSS and device
    redirection support for OSS.  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
    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
