The patch titled
drivers/block/cciss.c: fix check-after-use
has been removed from the -mm tree. Its filename was
drivers-block-ccissc-fix-check-after-use.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: drivers/block/cciss.c: fix check-after-use
From: Adrian Bunk <[EMAIL PROTECTED]>
The Coverity checker spotted that we have already oops'ed if "disk"
was NULL.
Since "disk" being NULL seems impossible at this point this patch
removes the NULL check.
