From 4aeb0e3283351351a5381a495ea24537f3bc21cb Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 1 Nov 2006 17:58:33 +0900 Subject: [PATCH] [PATCH] ahci: kill AHCI_FLAG_RESET_NEEDS_CLO Now that ahci_softreset() is fixed to automatically perform CLO if BSY/DRQ is set on entry, AHCI_FLAG_RESET_NEEDS_CLO is redundant. Kill it.
