Subject: [dpdk-dev] [PATCH 9/9] bus: remove useless plug parameter
Date: Sun, 9 Jul 2017 03:45:45 +0200 [thread overview]
Message-ID: <d721f3de73824c767b3e7df5aba378e4f35c49be.1499563730.git.gaetan.rivet@6wind.com> (raw)
In-Reply-To: <cover.1499563730.git.gaetan.rivet@6wind.com>
In-Reply-To: <cover.1499563730.git.gaetan.rivet@6wind.com>
The prior scan should link the relevant rte_devargs to the newly
allocated rte_device. As such, it is useless to pass device arguments to
the plug callback. Those arguments are available within the devargs
field of the rte_device structure.
Fixes: 7c8810f43f6e ("bus: introduce device plug/unplug")
Fixes: 00e62aae69c0 ("bus/pci: implement plug/unplug operations")
Fixes: a3ee360f4440 ("eal: add hotplug add/remove device")
