From d23511f9590870effa5ace575b59aac18c47175f Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 28 Nov 2011 18:50:39 +0000 Subject: [PATCH] regmap: Report if we actually handled an interrupt in regmap-irq While the IRQ core doesn't currently support shared threaded interrupts that's no reason for drivers not to do their bit and report IRQ_NONE when they don't get an interrupt. This allows the core spurious/wedget interrupt detection support to do its thing.
