Subject: [PATCH] em28xx-dvb: fix memleak in dvb_fini()
Date: Thu, 31 Dec 2009 12:47:11 +0100 [thread overview]
Message-ID: <1262260031.4401.9.camel@localhost> (raw)
Hi,
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.
Regards,
Francesco
