From 11d3d334af07408ce3a68860c40006ddcd343da5 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Mon, 7 Apr 2014 12:13:05 +0200 Subject: [PATCH] gpio: dwapb: drop irq_setup_generic_chip() The driver calls irq_alloc_domain_generic_chips() which creates a gc and adds it to gc_list. The driver later then calls irq_setup_generic_chip() which also initializes the gc and adds it to the gc_list() and this corrupts the list. Enable LIST_DEBUG and you see the kernel complain. This isn't required, irq_alloc_domain_generic_chips() did the init.
