Subject: [dpdk-dev] [PATCH v3 6/8] pci: fix generic driver pointer on probe error
Date: Wed, 12 Jul 2017 01:25:40 +0200 [thread overview]
Message-ID: <9474d104eb6aa07b7b156cdb884d2b6bbfd6c1ae.1499814957.git.gaetan.rivet@6wind.com> (raw)
In-Reply-To: <cover.1499814957.git.gaetan.rivet@6wind.com>
In-Reply-To: <cover.1499814957.git.gaetan.rivet@6wind.com>
The field is set but never resetted on error.
This marks the device as being attached while it is not, and forbid
further attempts to hotplug it.
Fixes: 7917d5f5ea46 ("pci: initialize generic driver pointer")
