From aac5987a54a25d243d3045d4ae33756a56498a5e Mon Sep 17 00:00:00 2001 From: Gustavo Padovan Date: Wed, 15 Feb 2017 15:55:31 -0200 Subject: [PATCH] [media] tw5864: improve subscribe event handling 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.
