From e5c9d1107a07c871c3ce0f55b7c175e043581900 Mon Sep 17 00:00:00 2001 From: Keerthi Reddy Date: Thu, 28 Sep 2017 20:28:40 +0530 Subject: [PATCH] Staging: vc04_services: remove unused variables the volatile fields of bcm2835_alsa_stream - control and status are not used. $ grep bcm2835_alsa_stream >From the above command all instances we see that all variables of 'bcm2835_alsa_stream' are declared as 'alsa_stream' So search for 'control' wherever we have 'alsa_stream' $ grep -l 'alsa_stream' | xargs grep "control" The above command returns where we don't any usage of 'control' field. which means that there is no usage of these fields. similarly for 'status' we see no usages.
