Currently poll_timeout_us() evaluates 'cond' twice at the end of the success case. This not desirable in case 'cond' itself is expensive. Avoid the double evaluation by tracking the return value in a variable. Need to use a triple undescore '___ret' name to avoid a conflict with an existing double undescore '__ret' variable in the regmap code.

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 reStructuredText 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.
