From e48031603ae644054a9251c6fc7f0e0fd4e2683a Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 6 Oct 2022 07:36:50 +0200 Subject: uio: uio_fsl_elbc_gpcm: Replace NO_IRQ by 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.
