Subject: Re: [PATCH v9 1/5] PCI: Conditionally initialize host bridge native_* members
Date: Tue, 22 Sep 2020 15:39:50 -0500 [thread overview]
Message-ID: <20200922203950.GA2227863@bjorn-Precision-5520> (raw)

I got 1/5, 3/5, and 5/5 (and no cover letter). Is there a 2/5 and a
4/5? Not sure if I should wait for more, or review these three as-is?
