From f188da4395b85698d1a55e9fb278ea7e629fbe96 Mon Sep 17 00:00:00 2001 From: Frank Schaefer Date: Sun, 12 Jan 2014 13:24:22 -0300 Subject: [PATCH] [media] em28xx-v4l: move v4l2_ctrl_handler freeing and v4l2_device unregistration to em28xx_v4l2_fini MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit v4l2_ctrl_handler_free() and v4l2_device_unregister() are currently only called when the last user closes the device and the device is already disconnected. But that's wrong, we need to call these functions whenever the em28xx-v4l extension is closed and we can already do this if the device is still opened by some users.
