Hi all,

After merging the sound-asoc-fixes tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

WARNING: modpost: sound/soc/snd-soc-core.o: section mismatch in reference: init_module (section: .init.text) -> snd_soc_util_exit (section: .exit.text)

Introduced by commit

   6ec27c53886c ("ASoC: core: Fix use-after-free in snd_soc_exit()")
It's because I called "_exit snd_soc_util_exit()" inside "_init snd_soc_init()".

Since snd_soc_util_exit is only used in snd_soc_init() and snd_soc_exit(), I think it's fine to remove _exit for snd_soc_util_exit().

Could you please add this change for the patch?

Thanks!
