Subject: [PATCH 0/2] video: fbdev: fix error handling, convert to pin_user_pages*()

Hi,

Note that I have only compile-tested this series, although that does
also include cross-compiling for a few other arches. I'm hoping that
this posting will lead to some run-time testing.

Also: the proposed fix does not have a "Fixes:" tag, nor does it
Cc stable. That's because the issue has been there since the dawn of
git history for the kernel. If it's gone unnoticed this long, then
there is clearly no need for the relatively fast track of putting it
into stable, IMHO. But please correct me if that's wrong.
