From: Thomas Petazzoni Date: Tue, 9 Apr 2013 21:26:16 +0000 (+0200) Subject: irqchip: armada-370-xp: move IRQ handler to avoid forward declaration X-Git-Tag: firefly_0821_release~3680^2~544^2~12^2~1 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=b313ada8c7a45e37e270bcaafef3f455fa9f4abf;p=firefly-linux-kernel-4.4.55.git irqchip: armada-370-xp: move IRQ handler to avoid forward declaration If we move the IRQ handler function above the initialization function, we avoid a forward declaration. This wasn't done as part of the previous commit, in order to increase the readibility of the previous commit, who was also moving the IRQ controller driver from arch/arm to drivers/irqchip.
