Subject: [PATCH 1/1] net: dsa: b53: Fix for failure when irq is not defined in dt
Date:   Thu,  7 Feb 2019 16:01:18 -0800
Message-Id: <20190208000118.9268-1-arun.parameswaran@broadcom.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Fixes the issues with non BCM58XX chips in the b53 driver
failing, when the irq is not specified in the device tree.

Removed the check for BCM58XX in b53_srab_prepare_irq(),
so the 'port->irq' will be set to '-EXIO' if the irq is not
specified in the device tree.

Fixes: 16994374a6fc ("net: dsa: b53: Make SRAB driver manage port interrupts")
Fixes: b2ddc48a81b5 ("net: dsa: b53: Do not fail when IRQ are not initialized")
