Subject: [PATCH] media: flexcop-usb: ensure -EIO is returned on error
condition
commit 74a96b51a36de4d86660fbc56b05d86668162d6b upstream.
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")
