can: c_can: reg_map_{c,d}_can: mark as __maybe_unused
This patch marks the arrays reg_map_c_can and reg_map_d_can as __maybe_unused,
as they are indeed unused in the c_can driver. This warning shows up, when
compiling the kernel with "W=1":
drivers/net/can/c_can/c_can.c:45:
drivers/net/can/c_can/c_can.h:124:18: warning: ‘reg_map_d_can’ defined but not used [-Wunused-const-variable=]
drivers/net/can/c_can/c_can.h:84:18: warning: ‘reg_map_c_can’ defined but not used [-Wunused-const-variable=]
