sound/usb/line6/driver.h:69:18: warning:
 SYSEX_DATA_OFS defined but not used [-Wunused-const-variable=]
sound/usb/line6/driver.h:70:18: warning:
 SYSEX_EXTRA_SIZE defined but not used [-Wunused-const-variable=]

SYSEX_EXTRA_SIZE is only used in driver.c and
SYSEX_DATA_OFS in pod.c, so move them to .c fix
this warning.

No, this makes things worse.  It should have been simply a normal
define instead.

Care to resend the fix with replacement to define?


thanks,
