Message-ID: <1303820929.12409.30.camel@erik-mbook> Date: Tue, 26 Apr 2011 14:28:49 +0200 From: Erik Botö <erik.boto@...agicore.com> To: linux-kernel@...r.kernel.org Cc: Grant Likely <grant.likely@...retlab.ca> Subject: [PATCH] gpio: pca953x: Use handle_simple_irq instead of handle_edge_irq Make pca953x driver use the simple irq handler since no hardware control is necessary and the driver lacks an irq_ack function. handle_edge_irq() calls chip->irq_ack() which crashes since this function does not exist.
