From 651a887f4e66b15145508e74db72ebb73c22112b Mon Sep 17 00:00:00 2001 From: John Baldwin Date: Mon, 25 Apr 2022 11:55:30 -0700 Subject: [PATCH] xen: Use devclass_find to lookup devclasses in identify. While here, use driver->name instead of hardcoding the xenpv and xen_et strings both for devclass_find() and BUS_ADD_CHILD().
