Subject: media: flexcop-usb: ensure -EIO is returned on error condition
Author: Colin Ian King <colin.k...@canonical.com>
Date: Fri Oct 25 15:33:39 2019 +0200
An earlier commit hard coded a return 0 to function flexcop_usb_i2c_req
even though the an -EIO was intended to be returned in the case where
ret != buflen. Fix this by replacing the return 0 with the return of
ret to return the error return code.
Addresses-Coverity: ("Unused value")
Fixes: b430eaba0be5 ("[media] flexcop-usb: don't use stack for DMA")
