Subject: [PATCH] ARM: OMAP3+: PRM: fix of_irq_get() result check
Git-commit: d683878dbeab3cd5cd073e40b41f24a4c7f62415
Patch-mainline: v4.14-rc1
References: bsc#1051510
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.
