Subject: [net-next PATCH v2 10/10] net: netcp: support probe deferral
Date: Tue, 27 Mar 2018 12:31:49 -0400 [thread overview]
Message-ID: <1522168309-12338-11-git-send-email-m-karicheri2@ti.com> (raw)
In-Reply-To: <1522168309-12338-1-git-send-email-m-karicheri2@ti.com>
The netcp driver shouldn't proceed until the knav qmss and dma
devices are ready. So return -EPROBE_DEFER if these devices are not
ready.
