Since commit | dd3bd23eb438 ("can: rcar_canfd: Add Renesas R-Car CAN FD driver") the rcar_canfd driver can be compile tested on all architectures. 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.
