--------------------------------

[ Upstream commit bbbd2549 ]

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: edd16368 ("hpsa: add driver for HP Smart Array controllers.")
