3.13.11-ckt30 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Takashi Iwai <tiwai@xxxxxxx> commit 225db5762dc1a35b26850477ffa06e5cd0097243 upstream. 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.
