From e0f17c75d9352c38926da1b4d8dbefc2d9942006 Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Sun, 22 Sep 2013 20:44:12 +0200 Subject: [PATCH] ALSA: Fix assignment of 0/1 to bool variables Convert 0 to false and 1 to true when assigning values to bool variables. Inspired by commit 3db1cd5c05f35fb43eb134df6f321de4e63141f2.
