Subject: [PATCH 1/3] gpio: dwapb: drop irq_setup_generic_chip()
Date: Thu, 20 Mar 2014 20:55:22 +0100 [thread overview]
Message-ID: <1395345324-18299-2-git-send-email-bigeasy@linutronix.de> (raw)
In-Reply-To: <1395345324-18299-1-git-send-email-bigeasy@linutronix.de>
This looks kinda wrong I didn't manage to fully test it.
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.
I can't find a single chip in tree which uses both functions so I think
that irq_setup_generic_chip() can be dropped.
