Subject[PATCH 4/6] [media] tw5864: improve subscribe event handling
Date
From: Gustavo Padovan <gustavo.padovan@collabora.com>

We already check for the V4L2_EVENT_CTRL inside
v4l2_ctrl_subscribe_event() so just move this function to the default:
branch of the switch and let it does the job for us.
