From 904dbd1307100edc12e2f98dd12b2338f1914f5b Mon Sep 17 00:00:00 2001 From: Alan Date: Mon, 8 Jan 2007 12:07:25 +0000 Subject: [PATCH] ahci: Remove jmicron fixup The AHCI set up is handled properly along with the other bits in the JMICRON quirk. Remove the code whacking it in ahci.c as its un-needed and also blindly fiddles with bits it doesn't own.
