This patch looks like it is a tiny change to get the pwm_backlight to
perform 64-bit division. Most of the above text is completely irrelevant
to the change contained in this patch. No need to justify the change in
the PWM structures here since that can go in the patch that changes
those structures.  Just describe what this patch does, perhaps something
like the following:

    The PWM API will shortly switch the state.period and
    state.duty_cycle fields to 64-bit values. Make pwm_bl
    ready for this transition by adopting 64-bit division
    macros.

Will update the commit text accordingly.

Also please copy the backlight maintainers into the covering letter. It
is useful to place patches like this into context.

Will do.

Thank you.
