[PATCH 0/1] x86/pci: Skip early E820 check for ECAM region

Posted by Bjorn Helgaas 1 week, 6 days ago

From: Bjorn Helgaas <bhelgaas@google.com>

This is a regression fix for
https://bugzilla.kernel.org/show_bug.cgi?id=218444,
"Lenovo Legion 9i Audio, TrackPad, Battery not detected"

Sorry that I failed to get this report onto the mailing list and regression
list earlier.
