From 787ab6e97024926f38773287d9f98a9b330bce23 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Wed, 18 May 2016 10:16:51 +0200 Subject: aacraid: do not activate events on non-SRC adapters Only SRC-based adapters support the AifReqEvent function, so there is no point in trying to activate it on older, non-SRC based adapters. Doing so lead to crashes on older adapters. Signed-off-by: Hannes Reinecke Reviewed-by: Johannes Thumshirn Reviewed-by: Raghava Aditya Renukunta Signed-off-by: Martin K.
