Subject: [PATCH v6 11/29] fpga: dfl: add dfl_fpga_check_port_id function.
Date: Tue, 12 Jun 2018 18:10:25 +0800	[thread overview]
Message-ID: <1528798243-2029-12-git-send-email-hao.wu@intel.com> (raw)
In-Reply-To: <1528798243-2029-1-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.
