This is a note to let you know that I have just added a patch titled ALSA: synth: Fix conflicting OSS device registration on AWE32 to the linux-3.19.y-queue branch of the 3.19.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.19.y-queue This patch is scheduled to be released in version 3.19.8-ckt10. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.19.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From d0bdd698a07ef0a6f8ceedf0e90c11683e03e45f Mon Sep 17 00:00:00 2001 From: Takashi Iwai <tiwai@suse.de> Date: Mon, 5 Oct 2015 16:55:09 +0200 Subject: [PATCH 025/120] ALSA: synth: Fix conflicting OSS device registration on AWE32 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.
