Subject: [PATCH 0/1] PCI/ASPM: Remove locking
Date: Thu, 10 Oct 2019 07:47:45 -0500
Message-ID: <20191010124746.2882-1-helgaas@kernel.org> (raw)

From: Bjorn Helgaas <bhelgaas@google.com>

In reference to this thread:
  https://lore.kernel.org/r/20191007223428.GA72605@google.com

This removes locking from pcie_aspm_enabled() because the reference count
held by the driver should provide all the locking we need.
