The patch titled
HiSax: fix error checking for hisax_register()]
has been removed from the -mm tree. Its filename was
hisax-fix-error-checking-for-hisax_register.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: HiSax: fix error checking for hisax_register()]
From: Alan Stern <[EMAIL PROTECTED]>
This patch (as875) adds error-checking to the callers of hisax_register().
It also changes an error pathway in that routine, making it return an error
code rather than 0.
This fixes Bugzilla #7960.
