Subject: ASoC: core: Make snd_soc_unregister_card() return void
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1892a991886ace2c3450bec801df2cf4028a803a;p=linux.git

ASoC: core: Make snd_soc_unregister_card() return void

The function snd_soc_unregister_card() returned 0 unconditionally and most
callers don't care to check the return value. Make it return void and
adapt the callers that didn't ignore the return value before.

This is a preparation for making platform remove callbacks return void.
