module: fix sprintf format specifier in param_get_byte()
In param_get_byte(), to which the macro STANDARD_PARAM_DEF(byte, ...) expands, "%c" is used to print an unsigned char. So it gets printed as a character what is not intended here. Use "%hhu" instead. [Rusty: note drivers which would be effected: drivers/net/wireless/cw1200/main.c drivers/ntb/ntb_transport.c:68 drivers/scsi/lpfc/lpfc_attr.c drivers/usb/atm/speedtch.c drivers/usb/gadget/g_ffs.c ] Acked-by: Jon Mason <jon.mason@intel.com> (for ntb) Acked-by: Michal Nazarewicz <mina86@mina86.com> (for g_ffs.c) Signed-off-by: Christoph Jaeger <christophjaeger@linux.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
