The format used for formatting SYSFS_FLAG_FW_SEL_BOOT creates the following warning: drivers/scsi/qedi/qedi_main.c:2259:35: warning: format specifies type 'char' but the argument has type 'int' [-Wformat] rc = snprintf(buf, 3, "%hhd\n", SYSFS_FLAG_FW_SEL_BOOT); Fix this to cast the constant as a char since the intention is to print it via sysfs as a byte.
