From: Mark Brown Date: Mon, 28 Nov 2011 18:50:39 +0000 (+0000) Subject: regmap: Report if we actually handled an interrupt in regmap-irq X-Git-Tag: firefly_0821_release~3680^2~3815^2~5^2~1 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d23511f9590870effa5ace575b59aac18c47175f;p=firefly-linux-kernel-4.4.55.git 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.
