    ALSA: synth: Fix conflicting OSS device registration on AWE32 · 225db576
    Takashi Iwai authored
    When OSS emulation is loaded on ISA SB AWE32 chip, we get now kernel
    warnings like:
      WARNING: CPU: 0 PID: 2791 at fs/sysfs/dir.c:31 sysfs_warn_dup+0x51/0x80()
      sysfs: cannot create duplicate filename '/devices/isa/sbawe.0/sound/card0/seq-oss-0-0'
    It's because both emux synth and opl3 drivers try to register their
    OSS device object with the same static index number 0.  This hasn't
    been a big problem until the recent rewrite of device management code
    (that exposes sysfs at the same time), but it's been an obvious bug.
    This patch works around it just by using a different index number of
    emux synth object.  There can be a more elegant way to fix, but it's
    enough for now, as this code won't be touched so often, in anyway.
