Subject[PATCH 3/5 v2] ASoC: nuc900: Fix platform_get_irq's error checking
Date
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.

changes in v2 :
nuc900_audio->irq_num is unsigned. so handle through signed variable.
