From 5e28e5fbdcf03907abea24b1bdc387333cebee38 Mon Sep 17 00:00:00 2001 From: Rajat Jain Date: Tue, 15 Nov 2016 19:06:03 +0530 Subject: [PATCH] mwifiex: Introduce mwifiex_probe_of() to parse common properties Introduce function mwifiex_probe_of() to parse common properties. Interface drivers get to decide whether or not the device tree node was a valid one (depending on the compatible property), Lets fill "adapter->dt_node" in mwifiex_add_card(). The function mwifiex_probe_of() is currently only a place holder with the next patch adding content to it.
