Your commit log doesn't actually describe what this change is...

This doesn't appear to correspond to the commit.  The change will result
in the driver automatically configuring it's PLL.

Please include human readable descriptions of things like commits and
issues being discussed in e-mail in your mails, this makes them much
easier for humans to read especially when they have no internet access.
I do frequently catch up on my mail on flights or while otherwise
travelling so this is even more pressing for me than just being about
making things a bit easier to read.

Unrelated (and questionable) whitespace change.
