This patch has been added to the 4.1 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit 1488a1e3828d60d74c9b802a05e24c0487babe4e ]
Since 34b48db66e08 ("block: remove artifical max_hw_sectors cap"),
max_sectors is no longer limited to BLK_DEF_MAX_SECTORS and LITE-ON
CX1-JB256-HP keeps timing out with higher max_sectors. Revert it to
the previous value.
