I am afraid you have the ES8316 codec, or one of its variants. /sys/bus/acpi/devices/ESSX8326:00/status 15 so no you don't want to use options snd-intel-dspcfg dsp_driver=1 but options snd-intel-dspcfg dsp_driver=3 The auto-detection don't work because we use a different codec HID for the driver selection { .flags = FLAG_SOF, .device = 0x5a98, .codec_hid = "ESSX8336", }, as well as the machine driver selection { .id = "ESSX8336", .drv_name = "sof-essx8336", .sof_tplg_filename = "sof-glk-es8336.tplg", }, This is really a problematic set of devices, where absolutely all possible I2S links have been used, along with GPIO settings and DMICs. Please file a bug on https://github.com/thesofproject/linux/issues so that we can keep track of this and suggest solution.

[PATCH] ASoC: Intel: atom: Remove redundant check to simplify the code
by Tang Bin 25 Jan '22

25 Jan '22

In the function sst_platform_get_resources(), if platform_get_irq() failed, the return should not be zero, as the example in platform.c is * int irq = platform_get_irq(pdev, 0) * if (irq < 0) * return irq; So remove the redundant check to simplify the code.

Hi All, This patch series has trivial changes for rz-ssi driver.

Patch 2/3 is from series [1] where a helper function is added and patch 3/3 is a new patch which removes duplicate macros.

[PATCH] kselftest: alsa: Add test case for writing invalid values
by Mark Brown 25 Jan '22

25 Jan '22

Attempt to write various invalid values for control types we know about and check that something sensible happens. The ABI isn't quite as clearly defined as one might like, rather than generating an error when an invalid value is written many devices will silently rewrite the value into one that is valid for the control. The exact value chosen is not predictable so in the case the write succeeds we just check that the value we read back is one that is valid for the control.

Make use of the struct_size() helper instead of an open-coded version, in order to avoid any potential type mistakes or integer overflows that, in the worst scenario, could lead to heap overflows.

Actually it seems that the WARN() can only be issued in two cases: - SPARC with vIRQ0 in one of the array member - fallback to ACPI for GPIO IRQ resource with index 0 But the latter is bogus, because it would mean a bug in the ACPI code. The bottom line here is the SPARC case. Anybody familiar with the platform can shed a light on this. If there is no such case, we may remove warning along with ret = 0 case from platfrom_get_irq(). > > 3.

I meant that instead of using special error code, 0 is very much good for the cases when IRQ is not found. It allows to distinguish -ENXIO from the low layer from -ENXIO with this magic meaning. > Additionally I see the problems: > > 4.

You are mixing up two things: - semantics of the pointer - semantics of the cookie Like I said previously the mistake is in putting an equal sign between apples and oranges (or in terms of Python, which is a good example here, None and False objects, where in both case 0 is magic and Python `if X`, `while `X` will work in the same way, the `typeof(X)` is different semantically). > For the idea to add a warning to platform_get_irq_optional for all but > -ENXIO (and -EPROBE_DEFER), I see the problem: > > 5. platform_get_irq*() issuing an error message is only correct most of > the time and given proper error handling in the caller (which might be > able to handle not only -ENXIO but maybe also -EINVAL[1]) the error message > is irritating.
