Subject: New Defects reported by Coverity Scan for Linux
Date: Tue, 10 Nov 2020 11:16:41 -0600 [thread overview]
Message-ID: <20201110171641.GA679781@bjorn-Precision-5520> (raw)
New Coverity complaint about v5.10-rc3, resulting from 9fff3256f93d
("PCI: dwc: Restore ATU memory resource setup to use last entry").
I didn't try to figure out if this is real or a false positive, so
just FYI.
