    ALSA: seq: Allow the tristate build of OSS emulation · 3d774d5e
    Takashi Iwai authored
    Currently OSS sequencer emulation is tied with ALSA sequencer core,
    both are built in the same level; i.e. when CONFIG_SND_SEQUENCER=y,
    the OSS sequencer emulation is also always built-in, even though the
    functionality can be built as an individual module.
    
    This patch changes the rule and allows users to build snd-seq-oss
    module while others are built-in.  Essentially, it's just a few simple
    changes in Kconfig and Makefile.  Some driver codes like opl3 need to
    convert from the simple ifdef to IS_ENABLED().  But that's all.
    
    You might wonder how about the dependency: right, it can be messy, but
    it still works.  Since we rewrote the sequencer binding with the
    standard bus, the driver can be bound at any time on demand.  So, the
    synthesizer driver module can be loaded individually from the OSS
    emulation core before/after it.
