From bed9829f3ec4b30d5cbec6511a11368ba5f169fb Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Wed, 13 Jul 2011 09:27:29 +0000 Subject: [PATCH] tg3: Check transitions to D0 power state Currently pci_set_power_state() does not return useful return codes for transitions to the D0 power state. If a device refuses to go into D0, the PCI layer issues a warning but returns success. Entering into D0 is a requirement for correct operation of tg3 devices though. If the PCI layer should be changed to return an error code for this type of failure, the tg3 driver would be interested in catching it and reacting to it. This patch makes the necessary modifications. Signed-off-by: Matt Carlson Signed-off-by: David S. Miller --- Reading git-format-patch failed
