Subject: [PATCH net-next 2/2] net: bgmac: Mask interrupts during probe
Date: Tue, 27 Mar 2018 16:20:02 -0700	[thread overview]
Message-ID: <20180327232002.29399-3-f.fainelli@gmail.com> (raw)
In-Reply-To: <20180327232002.29399-1-f.fainelli@gmail.com>

We can have interrupts left enabled form e.g: the bootloader which used
the network device for network boot. Make sure we have those disabled as
early as possible to avoid spurious interrupts.
