Never directly free @dev after calling device_register(), even if it returned an error! Always use put_device() to give up the reference initialized. Release allocated memory for vop device in vop_release_dev(). Signed-off-by: NArvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org>
