V4L/DVB (7108): radio-si470x.c: check-after-use
Adrian used the coverity checker against radio-si470x and found this: > The Coverity checker spotted the following check-after-use in > drivers/media/radio/radio-si470x.c: > > <-- snip --> > static void si470x_usb_driver_disconnect(struct usb_interface *intf) > { > struct si470x_device *radio = usb_get_intfdata(intf); > > del_timer_sync(&radio->timer); <------------------ > flush_scheduled_work(); > > usb_set_intfdata(intf, NULL); > if (radio) { <------------------ > video_unregister_device(radio->videodev); > kfree(radio->buffer); > kfree(radio); > } > } > <-- snip --> > > Either "radio" can be NULL and this case has to be properly handled or > the NULL check is not required. These two lines should indeed better be inside the if statement. Signed-off-by: Tobias Lorenz <tobias.lorenz@gmx.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
