Instead of allocating extra data in .request() provide the needed memory in struct berlin_pwm_chip. This reduces the number of allocations. A side effect is that on suspend and resume the state for all four channels is always saved and restored. This is easier (and probably quicker) than looking up the matching pwm_device and checking its PWMF_REQUESTED bit.

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.
