[ Upstream commit3f43926f27] The code in 'hci_dat_v1_get_index()' really looks like a hand coded version of 'for_each_set_bit()', except that a +1 is missing when searching for the next set bit. This really looks odd and it seems that it will loop until 'dat_w0_read()' returns the expected result. So use 'for_each_set_bit()' instead. It is less verbose and should be more correct.

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.
