The patch titled
via82cxxx: handle error condition properly
has been removed from the -mm tree. Its filename was
via82cxxx-handle-error-condition-properly.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: via82cxxx: handle error condition properly
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
Jeff noted that the via driver returned an error to an unsigned int in a
a case where errors are not permitted. Move the check down earlier so we
can handle it properly. Not as pretty but it works this way and avoids
hacking up ugly stuff in the legacy ide core.
