    ARM: rpc: check device_register return code in ecard_probe · 5f07809e
    Arnd Bergmann authored
    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]
