Subject: [PATCH 5.4 37/49] cxl: Rework error message for incompatible slots
Date: Sat, 31 Oct 2020 12:35:33 +0100 [thread overview]
Message-ID: <20201031113457.231477874@linuxfoundation.org> (raw)
In-Reply-To: <20201031113455.439684970@linuxfoundation.org>

commit 40ac790d99c6dd16b367d5c2339e446a5f1b0593 upstream.
Improve the error message shown if a capi adapter is plugged on a
capi-incompatible slot directly under the PHB (no intermediate switch).
