Subject[026/156] V4L/DVB (13961): em28xx-dvb: fix memleak in dvb_fini()
2.6.33-stable review patch.  If anyone has any objections, please let us know.


From: Francesco Lavra <>

commit 19f48cb105b7fa18d0dcab435919a3a29b7a7c4c upstream.

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.
