Subject: [PATCH] staging: comedi: usbduxsigma: remove redundant assignment to variable fx2delay

From: Colin Ian King <colin.king@...onical.com>

Variable fx2delay is being initialized with a value that is never read
and fx2delay is being re-assigned a little later on. The assignment is
redundant and hence can be removed.

Addresses-Coverity: ("Unused value")
