From 8b4f70ba4967cae90d128857af1382026a24230a Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Wed, 7 Jul 2010 15:36:07 +0200 Subject: [PATCH] firewire: cdev: fix fw_cdev_event_bus_reset emission after local config ROM changes When a descriptor was added or removed to the local node's config ROM, userspace clients which had a local node's /dev/fw* open did not receive any fw_cdev_event_bus_reset for poll()/read() consumption. The cause was that the core-device.c facility which re-reads the config ROM of the bus reset initiator node missed to call the fw_device update function. The fw_units are destroyed and newly added, but their parent stays and needs to be updated.
