From c825bc94c8c1908750ab20413eb639c6be029e2d Mon Sep 17 00:00:00 2001 From: Kenji Kaneshige Date: Tue, 16 Jun 2009 11:01:25 +0900 Subject: PCI hotplug: create symlink to hotplug driver module Create symbolic link to hotplug driver module in the PCI slot directory (/sys/bus/pci/slots/). In the past, we need to load hotplug drivers one by one to identify the hotplug driver that handles the slot, and it was very inconvenient especially for trouble shooting. With this change, we can easily identify the hotplug driver.
