The patch looks good now, but the changelog still needs a tiny bit of
work. First of all, your line wrapping is off, please start a new line
after around 70 characters as you do in an email.

Also, we don't normally have enumerated lists in a changelog, just use
normal text. The best changelogs typically have three paragraphs:

The first paragraph describes what the driver currently does. For really
obvious cases, this can be combined with the second paragraph.

The second paragraph explains why that is bad. This is where you can
mention the monotonic time vs real time issue and say whether we
just want the timeval removed to fix the kernel in general or whether
this particular driver is broken.

The third paragraph explains what the patch does to resolve the issue
described in the second one. This is also where you can list other
approaches that would have solved the problem, and why you picked on
over the others.
