[PATCH 3/6] [media] solo6x10: improve subscribe event handling

From: Gustavo Padovan
Date: Wed Feb 15 2017 - 12:56:08 EST


From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxx>

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