[PATCH] power: supply: cpcap-battery: Fix platform_get_irq_byname's error checking

From: Arvind Yadav
Date: Fri Nov 24 2017 - 12:02:04 EST


The platform_get_irq_byname() function returns -1 if an error occurs.
zero or positive number on success. platform_get_irq_byname() error
checking for zero is not correct.
