Subject: media: venus: mark PM functions as __maybe_unused
Author: Arnd Bergmann <a...@arndb.de>
Date: Mon Jul 17 04:56:47 2017 -0400
Without PM support, gcc warns about two unused functions:
platform/qcom/venus/core.c:146:13: error: 'venus_clks_disable' defined but not
used [-Werror=unused-function]
platform/qcom/venus/core.c:126:12: error: 'venus_clks_enable' defined but not
used [-Werror=unused-function]
The problem as usual are incorrect #ifdefs, so the easiest fix
is to do away with the #ifdef completely and mark the suspend/resume
handlers as __maybe_unused, which they are.
Fixes: af2c3834c8ca ("[media] media: venus: adding core part and helper
functions")
