From f3b017d8c9915cbaa8bab178dde1bd9dbbf5012c Mon Sep 17 00:00:00 2001 From: Ralph Wuerthner Date: Fri, 27 Oct 2006 12:39:26 +0200 Subject: [S390] Improve AP bus device removal. Added a call to device_unregister() in ap_scan_bus() to actively remove unavailable AP bus devices with every bus scan. Previously devices were only removed in ap_queue_message() or __ap_poll_all().
