Subject[PATCH 1/5 v2] ASoC: ep93xx-ac97: 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.

Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com>

changes in v2 :
irq was unsigned. so changed it to signed.
