From 4aa50bc9c2b2d5ab5c63658e0fadad03a08835cc Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Wed, 13 Jan 2010 12:05:45 +0100 Subject: pcmcia/bfin_cf: don't check platform_get_irq's return value against zero MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit platform_get_irq returns -ENXIO on failure, so !irq was probably always true. Better use irq <= 0. Note that a return value of zero is still handled as error even though this could mean irq0. This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that changed the return value of platform_get_irq from 0 to -ENXIO on error.
