X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=fa8cc38165c2f6f73bf947087b3cdc5dd9b9b560;p=openwrt%2Fstaging%2Fblogic.git

ASoC: nuc900: Fix platform_get_irq's error checking

The platform_get_irq() function returns negative if an error occurs.
zero or positive number on success. platform_get_irq() error checking
for zero is not correct.
