V4L/DVB (13961): em28xx-dvb: fix memleak in dvb_fini()
this patch fixes a memory leak which occurs when an em28xx card with DVB extension is unplugged or its DVB extension driver is unloaded. In dvb_fini(), dev->dvb must be freed before being set to NULL, as is done in dvb_init() in case of error. Note that this bug is also present in the latest stable kernel release.
