ALSA: sc6000: Keep the programmed board state in card-private data

2026-05-23T11:03:15+00:00

[ Upstream commit fb79bf127ac2577b4876132da6dba768018aad4c ] The driver may auto-select IRQ and DMA resources at probe time, but sc6000_init_board() still derives the SC-6000 soft configuration from the module parameter arrays. When irq=auto or dma=auto is used, the codec is created with the selected resources while the board is programmed with the unresolved values. Store the mapped ports and generated SC-6000 board configuration in card-private data, build that configuration from the live probe results instead of the raw module parameters, and keep the probe-time board programming in a shared helper. This fixes the resource-programming mismatch and leaves the driver with a stable board-state block that can be reused by suspend/resume.

ALSA: sc6000: Use standard print API

2026-05-23T11:03:15+00:00

[ Upstream commit e7c475b92043c02c3e6cd0c20e308fbb6f03ebde ] Use the standard print API with dev_*() instead of the old house-baked one. It gives better information and allows dynamically control of debug prints. Some functions are changed to receive a device pointer to be passed to dev_*() calls.

ALSA: sb: Force to disable DMAs once when DMA mode is changed

[ Upstream commit 4c267ae2ef349639b4d9ebf00dd28586a82fdbe6 ] When the DMA mode is changed on the (still real!) SB AWE32 after playing a stream and closing, the previous DMA setup was still silently kept, and it can confuse the hardware, resulting in the unexpected noises. As a workaround, enforce the disablement of DMA setups when the DMA setup is changed by the kcontrol. https://bugzilla.kernel.org/show_bug.cgi?id=218185 Link: https://patch.msgid.link/20250610064322.26787-2-tiwai@suse.de Signed-off-by: Takashi Iwai Signed-off-by: Sasha Levin
