Subject: [PATCH] ALSA: emu10k1: Fix annotation and cast for the recent uapi header change
Git-commit: 81b450909bfb4b71b4ae1c07add4feada32892bd
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518
The recent sound/emu10k1.h uapi header change by the commit
2e4688676392 ("ALSA: emu10k1: Make uapi/emu10k1.h compilable again")
made sparse angry because of the inconsistency of __user annotation
and the own ctl id struct that were changed in uapi header.
This patch addresses those by adjusting the cast and annotations
properly again.
Fixes: 2e4688676392 ("ALSA: emu10k1: Make uapi/emu10k1.h compilable again")
