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()")

Cheers,
Stephen Rothwell

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?
diff --git a/sound/soc/soc-utils.c b/sound/soc/soc-utils.c

Thanks!

I compiled linux-next/master and didn't find the warning.
Also I noticed that the fix patch 06ba770a799f ("ASoC: soc-utils: Remove
__exit for snd_soc_util_exit()") is on the tree.
Have no idea what's going wrong. Could you please check whether this
fixup takes effect?

That fix patch is in the sound-asoc tree (and makes the warning go
away), but the patch causing the warning is in the sound-asoc-fixes
tree ... so the latter patch needs to be moved into the
sound-asoc-fixes tree.
