From 08054200117a95afc14c3d2ed3a38bf4e345bf78 Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Thu, 23 Oct 2014 11:27:09 -0500 Subject: [PATCH] rtlwifi: Add check for get_btc_status callback Drivers that do not use the get_btc_status() callback may not define a dummy routine. The caller needs to check before making the call. Signed-off-by: Larry Finger Cc: Murilo Opsfelder Araujo Cc: Mike Galbraith Cc: Thadeu Cascardo Signed-off-by: John W.
