Bitmaps are defined on unsigned longs, so the usage of u32[2] in the wlcore driver is incorrect. As noted by Peter Zijlstra, casting arrays to a bitmap is incorrect for big-endian architectures. When looking at it I observed that: - operations on reg_ch_conf_pending is always under the wl_lock mutex, so set_bit is overkill - the only case where reg_ch_conf_pending is accessed a u32 at a time is unnecessary too. This patch cleans up everything in this area, and changes tmp_ch_bitmap to have the proper alignment.

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.
