From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The value from a readl is being masked with ITE_REG_CIOCAN_MASK however
this is not being used and cfg is being re-assigned. I believe the
assignment operator should actually be instead the |= operator.
Detected by CoverityScan, CID#1467987 ("Unused value")
