Subject: [PATCH] ALSA: Fix forgotten dependency fix for tristate OSS sequencer kconfig
Git-commit: f03293d8fc97f07dbe4c54ce495c8dac172dc6e1
Patch-mainline: v4.13-rc1
References: bsc#1121278
In the commit 3d774d5ef066 ("ALSA: seq: Allow the tristate build of
OSS emulation") we changed CONFIG_SND_SEQUENCER_OSS to tristate, but a
couple of places were forgotten, namely, opl3 and emux Makefile.
These contain the line like
snd-opl3-synth-$(CONFIG_SND_SEQUENCER_OSS) += opl3_oss.o
and this doesn't work any longer as expected because snd-opl3-synth
can be built-in while CONFIG_SND_SEQUENCER_OSS=m.
This patch fixes these places to build properly for the new kconfig
dependency. In the end, we had to use ifneq() to satisfy the
requirement. It's a bit ugly, but lesser evil.
