From f66abe92ce498672ac44d550f51a526597c731c4 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 24 Apr 2014 19:27:49 +0200 Subject: [PATCH] ACPI / notify: Do not block unknown type notifications in root handler MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Commit 1a699476e258 "ACPI / hotplug / PCI: Hotplug notifications from acpi_bus_notify()" changed the root notify handler, acpi_bus_notify(), to block unknown type norifications, but it overlooked the fact that they might be propagated to drivers via the ->notify() callback. Fix the problem by allowing drivers to receive unknown type notifications via ->notify() as before.
