The patch titled
hptiop: avoid buffer overflow when returning sense data
has been removed from the -mm tree. Its filename was
hptiop-avoid-buffer-overflow-when-returning-sense-data.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: hptiop: avoid buffer overflow when returning sense data
From: HighPoint Linux Team <linux@xxxxxxxxxxxxxxxxxx>
avoid buffer overflow when returning sense data.
With current adapter firmware the driver is working but future firmware
updates may return sense data larger than 96 bytes, causing overflow on
scp->sense_buffer and a kernel crash.
This fix should be backported to earlier kernels.
