Subject: [PATCH v2 0/2] media: dvb-usb: Fix UAF and memory leaks

Hi,

here is a revised patch set to address the use-after-free at
disconnecting a USB DVB device that was recently reported on openSUSE
Bugzilla.  The bug itself seems to be a long-standing one, and I
spotted another memory leak there, which is covered in the first
patch.

This revision addressed the double-free bug Sean pointed.

I added Robert's R-b tag only to patch#2, as patch#1 differs from the
v1 significantly.

thanks,

Takashi
