Subject[PATCH] [media] include/media: fix missing | operator when setting cfg
Date
From: Colin Ian King <colin.king@canonical.com>

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")
