Subject: [PATCH] ALSA: Make CONFIG_SND_OSSEMUL user-selectable
Git-commit: eb3b705aaed9cab7efef8c905eda919b5fd902b9
Patch-mainline: v4.13-rc1
References: bsc#1121278

Currently CONFIG_SND_OSSEMUL is selected by each config like
CONFIG_SND_PCM_OSS.  But, as see in the raw MIDI code that is built
conditionally with CONFIG_SND_OSSEMUL, we should rather make
CONFIG_SND_OSSEMUL user-selectable as the top kconfig item, and leave
the rest depending on it.
