Subject: [PATCH v4 4/5] r8152: Rename RTL8152_UNPLUG to RTL8152_INACCESSIBLE
Date:   Thu, 19 Oct 2023 14:20:23 -0700
Message-ID: <20231019142019.v4.4.Iaacab4e73761e7bd9bb622b30a804c5d20bd5b4c@changeid>
In-Reply-To: <20231019212130.3146151-1-dianders@chromium.org>
References: <20231019212130.3146151-1-dianders@chromium.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Whenever the RTL8152_UNPLUG is set that just tells the driver that all
accesses will fail and we should just immediately bail. A future patch
will use this same concept at a time when the driver hasn't actually
been unplugged but is about to be reset. Rename the flag in
preparation for the future patch.

This is a no-op change and just a search and replace.
