Subject: [PATCH] remoteproc/mtk_scp: surround DT device IDs with CONFIG_OF
Date: Mon,  2 Nov 2020 16:40:07 +0900	[thread overview]
Message-ID: <20201102074007.299222-1-acourbot@chromium.org> (raw)

Now that this driver can be compiled with COMPILE_TEST, we have no
guarantee that CONFIG_OF will also be defined. When that happens, a
warning about mtk_scp_of_match being defined but unused will be reported
so make sure this variable is only defined if of_match_ptr() actually
uses it.

Fixes: cbd2dca74926c0e4610c40923cc786b732c9e8ef remoteproc: scp: add COMPILE_TEST dependency
Reported-by: kernel test robot <lkp@intel.com>
