From 9621d872ca496eadb79399d0351abf96abc35338 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sun, 15 Jun 2008 11:10:13 +0000 Subject: [PATCH] (3/6) bcm57xx: preinit This patch allows the bcm57xx module to work correctly with failsafe mode. insmod doesn't return an error when a module loads but doesn't detect a switch. I added the check_module function to load the module, then make sure it doesn't just exit immediately. This allows preinit to only attempt to load the bcm57xx module when switch-robo and switch-adm dont detect a switch. The activate_gpio parameter to bcm57xx simply instructs the module to attempt to activate the switch via gpio before probing for the switch. Tested on wrt350n.
