In the past, I attempted to change the buffer management of the driver, but due to the lack of testing, it failed to get merged: https://lore.kernel.org/20191210154536.29819-1-tiwai@suse.de So, this is a second try after some years of gap: now the relevant code snippet is moved from ALSA core to dw-hdmi driver itself, and the API functions are dropped. There should be no functional changes in the driver. If DRM people don't mind and give an ack, I can take the change for dw-hdmi code together with ALSA core code drop via sound tree for 6.12. thanks, Takashi === Takashi Iwai (2): drm/bridge: dw-hdmi: Move vmalloc PCM buffer management into the driver ALSA: pcm: Drop PCM vmalloc buffer helpers .../drm/bridge/synopsys/dw-hdmi-ahb-audio.c | 30 ++++++++-- include/sound/pcm.h | 42 ------------- sound/core/pcm_memory.c | 59 ------------------- 3 files changed, 26 insertions(+), 105 deletions(-)
