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 6f7aff352e690bd167d97f8354543855cf6c34b8 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 10 Dec 2019 15:26:03 +0100 Subject: [PATCH] ASoC: stm32: Use managed buffer allocation Clean up the drivers with the new managed buffer allocation API. The superfluous snd_pcm_lib_malloc_pages() and snd_pcm_lib_free_pages() calls are dropped, as well as the superfluous snd_pcm_lib_preallocate_free_for_all() call. As of the result, hw_free and pcm_destruct ops became empty and got removed.
