On non OF enabled archs, or archs where OF is optional (and disabled in the .config) the compilation throws the following warning: | drivers/net/can/rcar/rcar_canfd.c:2020:34: warning: unused variable 'rcar_canfd_of_table' [-Wunused-const-variable] | static const struct of_device_id rcar_canfd_of_table[] = { | ^ This patch fixes the warning by marking the variable rcar_canfd_of_table as __maybe_unused.
