Hello there, linux-4.8-rc1/drivers/scsi/sd.c:317]: (style) Unsigned variable 'val' can't be negative so it is unnecessary to test it. Source code is if (val >= 0 && val <= SD_DIF_TYPE3_PROTECTION) but unsigned int val; Suggest new code if (val <= SD_DIF_TYPE3_PROTECTION) Regards David Binderman -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
