From d683878dbeab3cd5cd073e40b41f24a4c7f62415 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Tue, 15 Aug 2017 08:53:18 -0700 Subject: [PATCH] ARM: OMAP3+: PRM: fix of_irq_get() result check of_irq_get() may return 0 as well as a nagative error number on failure (and never on success), however omap3xxx_prm_late_init() regards 0 as a valid IRQ -- fix this.
