commit cca21000261b2364991ecdb0d9e66b26ad9c4b4e upstream.
Kernel test robot throws below warning ->
drivers/remoteproc/mtk_scp.c:755:37: warning: unused variable 'mt8183_of_data' [-Wunused-const-variable]
static const struct mtk_scp_of_data mt8183_of_data = { ^
drivers/remoteproc/mtk_scp.c:765:37: warning: unused variable 'mt8192_of_data' [-Wunused-const-variable]
static const struct mtk_scp_of_data mt8192_of_data = { ^ As suggested by Bjorn, there's no harm in just dropping the of_match_ptr() wrapping of mtk_scp_of_match in the definition of mtk_scp_driver and we avoid this whole problem.
