Subject: Re: [PATCH] hpfs: Remove unessary cast

Mikulas, when forwarding patches from others, you also need to add that

   "From: Firo Yang <firogm@...il.com>"

at the top (and it can be nice if you also add the date-line).
Otherwise authorship gets lost.

Sign-off lines _normally_ show the whole authorship chain too, but no,
it's not enough to just have the sign-off line there.
