[PATCH] usb: cdnsp: Fixes incorrect value in ISOC TRB

From: Pawel Laszczak
Date: Fri Mar 05 2021 - 00:01:04 EST


From: Pawel Laszczak <pawell@xxxxxxxxxxx>

The value "start_cycle ? 0 : 1" in assignment caused
implicit truncation whole value to 1 byte.
To fix the issue, an explicit casting has been added.

Fixes: commit 3d82904559f4 ("usb: cdnsp: cdns3 Add main part of Cadence USBSSP DRD Driver")
