From f668f074ff58dea540d83bbed1b2c1171b0dd764 Mon Sep 17 00:00:00 2001 From: Kevin Cernekee Date: Thu, 6 Nov 2014 22:44:21 -0800 Subject: [PATCH] irqchip: bcm7120-l2: Eliminate bad IRQ check This check may be prone to race conditions, e.g. 1) Some external event (e.g. GPIO level) causes an IRQ to become pending 2) Peripheral asserts the L2 IRQ 3) CPU takes an interrupt 4) The event from #1 goes away 5) bcm7120_l2_intc_irq_handle() reads back a 0 status Unlike the hardware supported by brcmstb-l2, the bcm7120-l2 controller does not latch the IRQ status. Bits can change if the inputs to the controller change. Also, do_bad_IRQ() is an ARM-specific macro. So let's just nuke it.
