You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark From 787126ebdb9821f1a19b1dfd1ab1bbb74b8c80b8 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sun, 26 Jul 2015 19:04:58 +0200 Subject: [PATCH] ASoC: dapm: Drop always true checks list_first_entry() always returns non NULL and since the code previously checked that list is not empty it will also be a valid pointer. Furthermore a path has always a sink or a source widget. So both checks are redundant and can be removed.
