+Subject: libata: LITE-ON CX1-JB256-HP needs lower max_sectors
+Origin: https://git.kernel.org/linus/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.
