From 7ddd4cd5c31ccaf32febe52462f9fdc915893212 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 20 Oct 2014 19:36:34 +0200 Subject: [PATCH] ASoC: dapm: Remove always true path source/sink checks A path has always a valid source and a valid sink otherwise we wouldn't add it in the first place. Hence all tests that check if sink/source is non NULL always evaluate to true and can be removed.
