Subject: [PATCH net-next 02/10] net/smc: remove useless smc_ib_devices_list check
Date: Mon, 10 Apr 2017 14:57:57 +0200	[thread overview]
Message-ID: <20170410125805.13653-3-ubraun@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170410125805.13653-1-ubraun@linux.vnet.ibm.com>

The global event handler is created only, if the ib_device has already
been used by at least one link group. It is guaranteed that there exists
the corresponding entry in the smc_ib_devices list. Get rid of this
superfluous check.
