From 1dea5edc90855cab8359b599128e3f322803cd09 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 6 Oct 2022 07:17:07 +0200 Subject: ata: pata_mpc52xx: Replace NO_IRQ with 0 NO_IRQ is used to check the return of irq_of_parse_and_map(). On some architecture NO_IRQ is 0, on other architectures it is -1. irq_of_parse_and_map() returns 0 on error, independent of NO_IRQ. So use 0 instead of using NO_IRQ.
