Waveform parameters are supposed to be rounded down to the next value possible for the hardware. However when a requested value is too small, .round_waveform_tohw() is supposed to pick the next bigger value and return 1. Let pwm_set_waveform() behave in the same way. This creates consistency between pwm_set_waveform_might_sleep() with exact=false and pwm_round_waveform_might_sleep() + pwm_set_waveform_might_sleep() with exact=true. The PWM_DEBUG rounding check has to be adapted to only trigger if no uprounding happend.

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.
