A new build error appeared with CONFIG_PROC_FS disabled:
arch/arm/mach-rpc/ecard.c:646:12: error: 'ecard_devices_proc_show' defined but
not used [-Werror=unused-function]
This marks the function as __maybe_unused to let the compiler drop
it silently.
Fixes: 3f3942aca6da ("proc: introduce proc_create_single{,_data}")
