Subject: [PATCH 02/10] Input: omap4-keypad: Fix platform_get_irq's error checking
Date:   Sat, 18 Nov 2017 00:45:24 +0530
Message-Id: <1510946132-13554-3-git-send-email-arvind.yadav.cs@gmail.com>
In-Reply-To: <1510946132-13554-1-git-send-email-arvind.yadav.cs@gmail.com>
References: <1510946132-13554-1-git-send-email-arvind.yadav.cs@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
