The patch titled
via-rhine: revert "change mdelay to msleep and remove from ISR path"
has been removed from the -mm tree. Its filename is
via-rhine-revert-change-mdelay-to-msleep-and-remove-from-isr-path.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.

Subject: via-rhine: revert "change mdelay to msleep and remove from ISR path"
From: Roger Luethi <rl@xxxxxxxxxxx>
Patch from John W. Linville. I didn't test it, but I support reverting the
earlier patch.
Revert previous patch with subject "change mdelay to msleep and remove
from ISR path". This patch seems to have caused bigger problems than
it solved, and it didn't solve much of a problem to begin with...
