From cb59c87dbc8be2ffa692c50bd22f89025ba7a342 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Thu, 10 Jan 2013 06:58:43 +0000 Subject: [PATCH] net: ethernet: xilinx: Do not use NO_IRQ in axienet This driver is used on Microblaze and will be used on Arm Zynq. Microblaze doesn't define NO_IRQ and no IRQ is 0. Arm still uses NO_IRQ as -1 and there is no option to connect IRQ to irq 0. That's why <= 0 is only one option how to find out undefined IRQ.
