From 6508281b0b15c469a940ffa46bb9215c9e18eaf3 Mon Sep 17 00:00:00 2001 From: Vladimir Kondratiev Date: Mon, 14 Jul 2014 09:49:37 +0300 Subject: [PATCH] wil6210: support for "sparrow" hardware New hardware release appears; it require some changes to properly support it. Introduce struct wil_board and "board" attribute in wil6210_priv; keep hardware variant information in this structure. fill it on probe(). Used in the reset flow.
