From 715f67f33af45ce2cc3a5b1ef133cc8c8e7787b0 Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Fri, 20 Oct 2023 14:06:58 -0700 Subject: [PATCH] r8152: Rename RTL8152_UNPLUG to RTL8152_INACCESSIBLE 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. Signed-off-by: Douglas Anderson Reviewed-by: Grant Grundler Signed-off-by: David S.
