From 1488a1e3828d60d74c9b802a05e24c0487babe4e Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 18 Jul 2016 18:40:00 -0400 Subject: [PATCH] libata: LITE-ON CX1-JB256-HP needs lower max_sectors 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.
