From: Shreyansh Jain Date: Fri, 25 Aug 2017 10:19:54 +0000 (+0530) Subject: bus/fslmc: refactor scan and probe functions X-Git-Tag: spdx-start~2122 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=828d51d8fc3e;p=dpdk.git bus/fslmc: refactor scan and probe functions Scan now searches for devices through sysfs interface and adds them to a list for later initialization. During probe, each device is initialized accroding to its property.
