From: Uwe Kleine-König Date: Wed, 9 Feb 2011 10:28:04 +0000 (+0100) Subject: don't check platform_get_irq's return value against zero X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c7d876321f4cf252bc70c1995bbc077a65b3af2a;p=openwrt%2Fstaging%2Fblogic.git don't check platform_get_irq's return value against zero platform_get_irq returns -ENXIO on failure, so !int_irq was probably always true. Better use (int)int_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.
