From 235af943fa5a8c818a63027485169c0fa61f243b Mon Sep 17 00:00:00 2001 From: Frank Schaefer Date: Mon, 24 Mar 2014 16:33:08 -0300 Subject: [PATCH] upstream: [media] em28xx-video: simplify usage of the pointer to struct v4l2_ctrl_handler in em28xx_v4l2_init() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The local var hdl is already pointing to &dev->ctrl_handler. Use it, instead of dereferencing it all the time. Code cleanup. No functional changes.
