"Code is wrong, make code right"


I find it hard to believe that "the clock configuration is wrong" takes
207 lines of code to address.

Please instead describe the problem you're solving, to ensure that
current and future readers of this commit message have a chance to
understand why this change was made.

The "describing your changes" section in the documentation is good,
please read it:
https://docs.kernel.org/process/submitting-patches.html#describe-your-changes
