[PATCH 6.1 024/194] r8152: Rename RTL8152_UNPLUG to RTL8152_INACCESSIBLE

11 Dec 2023

6.1-stable review patch.  If anyone has any objections, please let me know.
------------------
From: Douglas Anderson dianders@chromium.org
[ Upstream commit 715f67f33af45ce2cc3a5b1ef133cc8c8e7787b0 ]
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.
