Thanks, I'll add it to misc-5.2, the type of the fix qualifies for a
late rc, so I'll send it by the end of the week.

I'd prefer to get patches instead of links to dropbox. You can send more
patches in a series or as a reply to one of them and put the expected
target version to the subject to eg. like [PATCH for 5.2] or [PATCH for
<= 5.1] and put the note like the above with further details. Thanks.
