We have the distinction between pwm_apply_atomic() and pwm_apply_might_sleep() since commitc748a6d77c(pwm: Rename pwm_apply_state() to pwm_apply_might_sleep()) contained in v6.8-rc1. Locking in the core was introduced in commit1cc2e1faaf("pwm: Add more locking", contained in v6.13-rc1) to serialize per-chip callbacks and device removal.

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.
