ARM: OMAP4+: PRM: fix of_irq_get() result checks
of_irq_get() may return 0 as well as a nagative error number on failure, (and never on success), however omap44xx_prm_late_init() regards 0 as a valid IRQ -- fix this. Fixes: a8f83aefcd5a ("ARM: OMAP4+: PRM: register interrupt information from DT") Fixes: c5b3955828ba ("ARM: OMAP4: Fix legacy code clean-up regression") Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
