ASoC: Intel: avoid Oops if DMA setup fails

2019-05-10T16:36:14Z

commit 0efa3334d65b7f421ba12382dfa58f6ff5bf83c4 upstream. Currently in sst_dsp_new() if we get an error return from sst_dma_new() we just print an error message and then still complete the function successfully. This means that we are trying to run without sst->dma properly set up, which will result in NULL pointer dereference when sst->dma is later used. This was happening for me in sst_dsp_dma_get_channel(): struct sst_dma *dma = dsp->dma; ... dma->ch = dma_request_channel(mask, dma_chan_filter, dsp); This resulted in: BUG: unable to handle kernel NULL pointer dereference at 0000000000000018 IP: sst_dsp_dma_get_channel+0x4f/0x125 [snd_soc_sst_firmware] Fix this by adding proper error handling for the case where we fail to set up DMA. This change only affects Haswell and Broadwell systems. Baytrail systems explicilty opt-out of DMA via sst->pdata->resindex_dma_base being set to -1.

ASoC: Intel: kbl_rt5660: Add a new machine driver for kbl with rt5660

2018-12-13T14:37:35Z

The new Dell IoT platform uses kabylake + alc3277 codec, and alc3277 shares the driver with the codec rt5660, here we generate a new machine driver based on kbl_da7219_max98357a. The audio design on this IoT platform is as below: - Intel kabylake platform - connect the codec ALC3277 via SSP0 - line-out and line-in with Micbias jacks - line-out mute control and jack detection of line-out and line-in - two HDMI ports with audio capability Signed-off-by: Hui Wang Acked-by: Pierre-Louis Bossart Signed-off-by: Mark Brown

ASoC: Intel: common: add quirk for APL RVP boards

2018-11-06T17:25:07Z

For some reason the RVP/LeafHill SSDT exposes an INT34C3 ID which is used on other boards to point to the TDF8532 amplifier. Yay BIOS. Add a DMI-quirk to ignore this ID and check for other valid machine driver descriptors. Reviewed-by: Andy Shevchenko Signed-off-by: Pierre-Louis Bossart Signed-off-by: Mark Brown

ASoC: Intel: common: add table for HDA-based platforms

2018-08-28T19:18:07Z

Expose a table containing machine driver information for HDAudio-based platforms handled by ASoC on Intel hardware. We only set constant values that are valid across multiple platforms. The firmware name used by the DSP will be set dynamically for each platform. The table is made of a single entry for now, if we need more complicated set-up where HDAudio is mixed with ACPI-enumerated devices (I2C, SoundWire) then we'd expect the differentiation to be handled through information provided by the BIOS (as done for KBL Chromebooks).

Also add these typos to spelling.txt so checkpatch.pl will look for them.
