Subject: [PATCH v4 6/6] GPIO: pca953x.c: Add missing irq_mask_ack handler in struct irq_chip
Date: Wed, 8 Jun 2011 14:48:34 +0200 [thread overview]
Message-ID: <1307537314-4345-7-git-send-email-david@protonic.nl> (raw)
In-Reply-To: <1307537314-4345-1-git-send-email-david@protonic.nl>
Either .irq_mask_ack or .irq_ack need to be filled in, otherwise in
kernel/irq/chip.c: mask_ack_irq() a non-initialized handler is called.
