Subject: don't check platform_get_irq's return value against zero
X-Git-Tag: v2.6.39-rc4~56^2~1
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c7d876321f4cf252bc70c1995bbc077a65b3af2a;p=pandora-kernel.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.
