Subject: [PATCH v4 5/6] GPIO: pca953x.c: Fix warning of enabled interrupts in handler
Date: Wed, 8 Jun 2011 14:48:33 +0200 [thread overview]
Message-ID: <1307537314-4345-6-git-send-email-david@protonic.nl> (raw)
In-Reply-To: <1307537314-4345-1-git-send-email-david@protonic.nl>
When using nested threaded irqs, use handle_nested_irq(). This function
does not call the chip handler, so no handler is set.
