From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The early initialization of val is redundant as the value is never
read and is updated inside a for-loop. Remove the initialization
and move the declaration and initialization to the for-loop scope.
Cleans up clang warning:
drivers/staging/comedi/drivers/usbdux.c:812:15: warning: Value stored
to 'val' during its initialization is never read
