Jia-Ju Bai ec2e93cf19 b43: Avoid possible double calls to b43_one_core_detach()
In b43_request_firmware(), when ieee80211_register_hw() fails,
b43_one_core_detach() is called. In b43_bcma_remove() and
b43_ssb_remove(), b43_one_core_detach() is called again. In this case,
null-pointer dereferences and double-free problems can occur when
the driver is removed.

To fix this bug, the call to b43_one_core_detach() in
b43_request_firmware() is deleted.

This bug is found by a runtime fuzzing tool named FIZZER written by us.

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.
