Subject: [PATCH 1/10 v2] Input: ep93xx_keypad: Fix platform_get_irq's error checking
Date: Sat, 18 Nov 2017 01:50:01 +0530	[thread overview]
Message-ID: <a9a25cd5775ba4c76d47e8b66934e470f58d9e72.1510949239.git.arvind.yadav.cs@gmail.com> (raw)

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.
