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 eea3dd4f1247aa8654194fb19ade22c94c42e41a Mon Sep 17 00:00:00 2001 From: Mengdong Lin Date: Fri, 25 Nov 2016 16:09:17 +0800 Subject: [PATCH] ASoC: topology: Only free TLV for volume mixers of a widget This patch will check the type of embedded controls for a widget, and only free the TLV of volume mixers. Bytes controls don't have TLV. Just free the private value which is used as struct soc_mixer_control for volume mixers or soc_bytes_ext for bytes controls. No need to cast to these types before freeing it.
