From 5d36e56fb934c435ab49a57b62512bf44930a63c Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 17 Sep 2009 00:34:39 +0900 Subject: [PATCH] ahci: restore pci_intx() handling Commit 4393e8ba62b82e975e5b3db4855ef992998649d0 dropped explicit pci_intx() manipulation from ahci because it seemed unnecessary and ahci doesn't seem to be the right place to be tweaking it if it were. This was largely okay but there are exceptions. There was one on an embedded platform which was fixed via firmware and now bko#14124 reports it on a HP DL320. http://bugzilla.kernel.org/show_bug.cgi?id=14124 I still think this isn't something libata drivers should be caring about (the only ones which are calling pci_intx() explicitly are libata ones and one other driver) but for now reverting the change seems to be the right thing to do.
