Subject: [PATCH v1 0/2]: PCI: PM: Improvements related to D3cold -> D0 transitions
Date: Mon, 04 Apr 2022 17:38:58 +0200	[thread overview]
Message-ID: <4198163.ejJDZkT8p0@kreacher> (raw)

Hi All,

This series of two patches addresses potential issues related to transitions
of PCI devices from D3cold to D0.

The first one is that devices initially in D3cold may be left in D0-uninitialized
by pci_power_up() in some cases and the second one is that attempting to resume
PCI devices under a bridge that fails to go from D3cold to D0 is pointless.

Please refer to the patch changelogs for details.

Thanks!
