Date: Wed, 14 Sep 2011 11:57:55 +0300 From: Tero Kristo <t-kristo@...com> To: <linux-kernel@...r.kernel.org> Subject: [PATCH] irq: call also chip->irq_mask from irq_disable Current implementation of the irq_disable only calls chip->irq_disable. This fails to disable interrupt on some chip implementations, as there are two alternative chip specific functions for this task, chip->irq_disable and chip->irq_mask. Added alternative path for chip->irq_disable also.
