From b53046cbf8c90ca67a818c9093227e60cf1387b6 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 6 Sep 2016 15:53:29 +0200 Subject: [PATCH] mfd: ucb1x00: Remove NO_IRQ check probe_irq_off() returns '0' on failure, not NO_IRQ, so the check in this driver is clearly wrong. This replaces it with the regular '!irq' check used in other drivers. The sa1100 platform that this driver is used on originally numbered all its interrupts starting at '0', which would have conflicted with this change, but as of commit 18f3aec ("ARM: 8230/1: sa1100: shift IRQs by one"), this is not a problem any more.
