[ Upstream commit 589a9f0eb799f77de2c09583bf5bad221fa5d685 ] dvb_usb_device_init stores parts of properties at d->props and d->desc and uses it on dvb_usb_device_exit. Free of properties on module probe leads to use after free. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=204597 The patch makes properties static instead of allocated on heap to prevent memleak and use after free. Also fixes s421_properties.devices initialization to have 2 element instead of 6 copied from p7500_properties.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
