Subject: [PATCH 3/7] gpio: dwapb: drop irq_setup_generic_chip()
Date: Sat, 22 Mar 2014 17:16:40 +0100	[thread overview]
Message-ID: <1395505004-22650-4-git-send-email-bigeasy@linutronix.de> (raw)
In-Reply-To: <1395505004-22650-1-git-send-email-bigeasy@linutronix.de>

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.
