New Revision: 281873
URL: https://svnweb.freebsd.org/changeset/base/281873
Log:
Don't explicitly manage power states for PCI-PCI bridge devices in the
driver's suspend and resume routines. These have been redundant no-ops
since r214065 changed the PCI bus driver to manage power states for
all devices (including type 1/2 bridge devices) during suspend and resume.
