alloc_pwms() only identified a free range of IDs and this range was marked as used only later by pwmchip_add(). Instead let alloc_pwms() already do the marking (which makes the function actually allocating the range and so justifies the function name). This way access to the allocated_pwms bitfield is limited to two functions only.

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.
