From 9a0b062742e7e039273c0c2ba4b96ad9ec7e7d8f Mon Sep 17 00:00:00 2001 From: Alexandre Bounine Date: Tue, 22 Mar 2016 14:26:44 -0700 Subject: rapidio: add global inbound port write interfaces Add new Port Write handler registration interfaces that attach PW handlers to local mport device objects. This is different from old interface that attaches PW callback to individual RapidIO device. The new interfaces are intended for use for common event handling (e.g. hot-plug notifications) while the old interface is available for individual device drivers. This patch is based on patch proposed by Andre van Herk but preserves existing per-device interface and adds lock protection for list handling.
