Subject: [PATCH v3 06/21] fpga: dfl: adds fpga_cdev_find_port
Date: Mon, 27 Nov 2017 14:42:13 +0800 [thread overview]
Message-ID: <1511764948-20972-7-git-send-email-hao.wu@intel.com> (raw)
In-Reply-To: <1511764948-20972-1-git-send-email-hao.wu@intel.com>
For feature devices, e.g FPGA Management Engine (FME), it may
require fpga_cdev_find_port function to find dedicate port for
further actions, so export this function from feature device
driver module.
