From 979b1791e5b8f8b556faeec4c48339e7ed63af9f Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Thu, 24 Jul 2008 17:18:38 +0100 Subject: PCI: add D3 power state avoidance quirk Libata has some hacks to deal with certain controllers going silly in D3 state. The right way to handle this is to keep a PCI device flag for such devices. That can then be generalised for no ATA devices with power problems.
