Subject: [PATCH 2/6] mmc: s3cmci: Fix platform_get_irq's error checking
Date: Sat, 18 Nov 2017 01:58:18 +0530	[thread overview]
Message-ID: <1510950502-22565-3-git-send-email-arvind.yadav.cs@gmail.com> (raw)
In-Reply-To: <1510950502-22565-1-git-send-email-arvind.yadav.cs@gmail.com>

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.
