Subject: ASoC: pcm1789: Make pcm1789_common_exit() return void
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6cefb6264277c073030a3b2d91ba6b28593b4c89;p=linux.git

ASoC: pcm1789: Make pcm1789_common_exit() return void

This function returns zero unconditionally, so there isn't any benefit
of returning a value. Make it return void to be able to see at a glance
that the return value of pcm1789_i2c_remove() is always zero.

This patch is a preparation for making i2c remove callbacks return void.
