      ALSA: i2c: ak4xxx-adda: Fix a possible null pointer dereference in build_adc_controls() · 2127c01b
      Jia-Ju Bai authored 
      

In build_adc_controls(), there is an if statement on line 773 to check
whether ak->adc_info is NULL:
    if (! ak->adc_info ||
        ! ak->adc_info[mixer_ch].switch_name)

When ak->adc_info is NULL, it is used on line 792:
    knew.name = ak->adc_info[mixer_ch].selector_name;

Thus, a possible null-pointer dereference may occur.

To fix this bug, referring to lines 773 and 774, ak->adc_info
and ak->adc_info[mixer_ch].selector_name are checked before being used.

This bug is found by a static analysis tool STCheck written by us.

      ALSA: hda - Show the fatal CORB/RIRB error more clearly · dd65f7e1
      Takashi Iwai authored 
      

The last fallback of CORB/RIRB communication error recovery is to turn
on the single command mode, and this last resort usually means that
something is really screwed up.  Instead of a normal dev_err(), show
the error more clearly with dev_WARN() with the caller stack trace.

Also, show the bus-reset fallback also as an error, too.

      dt-bindings: pinctrl: stm32: Fix missing 'clocks' property in examples · e2297f7c
      Rob Herring authored 
      Now that examples are validated against the DT schema, an error with
required 'clocks' property missing is exposed:

Documentation/devicetree/bindings/pinctrl/st,stm32-pinctrl.example.dt.yaml: \
pinctrl@40020000: gpio@0: 'clocks' is a required property
Documentation/devicetree/bindings/pinctrl/st,stm32-pinctrl.example.dt.yaml: \
pinctrl@50020000: gpio@1000: 'clocks' is a required property
Documentation/devicetree/bindings/pinctrl/st,stm32-pinctrl.example.dt.yaml: \
pinctrl@50020000: gpio@2000: 'clocks' is a required property

Add the missing 'clocks' properties to the examples to fix the errors.

Fixes: 2c9239c1

      dt-bindings: iio: ad7124: Fix dtc warnings in example · 20051f5f
      Rob Herring authored 
      With the conversion to DT schema, the examples are now compiled with
dtc. The ad7124 binding example has the following warning:

Documentation/devicetree/bindings/iio/adc/adi,ad7124.example.dts:19.11-21: \
Warning (reg_format): /example-0/adc@0:reg: property has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1)

There's a default #size-cells and #address-cells values of 1 for
examples. For examples needing different values such as this one on a
SPI bus, they need to provide a SPI bus parent node.

Fixes: 26ae15e6
