ARM: rpc: check device_register return code in ecard_probe
device_register is marked __must_check, so we better propagate the error value by returning it from ecard_probe. Without this patch, building rpc_defconfig results in: arch/arm/mach-rpc/ecard.c: In function 'ecard_probe': arch/arm/mach-rpc/ecard.c:963:17: warning: ignoring return value of 'device_register', declared with attribute warn_unused_result [-Wunused-result] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Russell King <rmk+kernel@arm.linux.org.uk>
