Subject: [PATCH] media: cec: set ev rather than v with CEC_PIN_EVENT_FL_DROPPED bit

From: Colin Ian King <colin.king@...onical.com>

Setting v with the CEC_PIN_EVENT_FL_DROPPED is incorrect, instead
ev should be set with this bit. Fix this.

Detected by CoverityScan, CID#1467974 ("Extra high-order bits")
