Subject: [PATCH v7 11/29] fpga: dfl: add dfl_fpga_check_port_id function.
Date: Sat, 30 Jun 2018 08:53:18 +0800	[thread overview]
Message-ID: <1530320016-24712-12-git-send-email-hao.wu@intel.com> (raw)
In-Reply-To: <1530320016-24712-1-git-send-email-hao.wu@intel.com>

This patch adds one common function in DFL framework. It uses
port_ops get_id callback to get port id and compare it with given
value. This function could be used as match function of the
dfl_fpga_cdev_find_port function.

Signed-off-by: Wu Hao <hao.wu@intel.com>
Acked-by: Alan Tull <atull@kernel.org>
---
v6: reabse and add Acked-by from Alan.
