Subject: [PATCH 03/10] net: ezchip: nps_enet: Fix platform_get_irq's error checking
Date: Sun, 3 Dec 2017 00:56:15 +0530 [thread overview]
Message-ID: <1512242782-7134-4-git-send-email-arvind.yadav.cs@gmail.com> (raw)
In-Reply-To: <1512242782-7134-1-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. And remove unnecessary check for free_netdev().
