Subject: ASoC: rt286: Fix compilation warning for !PM
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=81f3dfe1908011ee12760ce4d75451e7446dff80;p=linux-beck.git

ASoC: rt286: Fix compilation warning for !PM

The rt286_index_sync() function is only called in the resume path. If PM
is disabled it becomes unused and shouldn't be built either.
