From 09185a5999c733ec37220ad4a0baa7598a2044d2 Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 30 Aug 2016 12:00:25 +0100 Subject: [PATCH] mfd: ucb1x00: Allow IRQ probing to work with IRQs > 32 probe_irq_on() only returns non-zero if it found any interrupts below IRQ32 which could be probe candidates. If all the probable interrupts are higher than 32, then this will cause a failure. Fix this.
