The same is done almost everywhere in kernel tree : e.g : http://lxr.free-electrons.com/source/drivers/staging/iio/adc/mxs-lradc.c#L928 http://lxr.free-electrons.com/source/drivers/gpio/gpio-mxs.c#L292 http://lxr.free-electrons.com/source/drivers/iommu/tegra-smmu.c#L1181 http://lxr.free-electrons.com/source/drivers/rtc/rtc-spear.c#L388 http://lxr.free-electrons.com/source/drivers/i2c/busses/i2c-imx.c#L514 http://lxr.free-electrons.com/source/sound/soc/kirkwood/kirkwood-i2s.c#L475 and so on... all theses functions return an int.
