+Subject: scsi: hpsa: Fix allocation size for scsi_host_alloc()
+
+From: Alexey V. Vissarionov <gremlin@altlinux.org>
+
+[ Upstream commit bbbd25499100c810ceaf5193c3cfcab9f7402a33 ]
+
+The 'h' is a pointer to struct ctlr_info, so it's just 4 or 8 bytes, while
+the structure itself is much bigger.
+
+Found by Linux Verification Center (linuxtesting.org) with SVACE.
+
+Fixes: edd163687ea5 ("hpsa: add driver for HP Smart Array controllers.")
