From 31cef7076ed9409a33f19ea372d6dc5fdefe27ae Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 2 Nov 2009 09:34:16 +0100 Subject: control: remove snd_konctrol_volatile::owner_pid field We do not need to save the ID of the process that locked a control because that information is already available in the owner's file data.
