[PATCH 0/3] ASoC: SOF: Intel: hda: Correct Firmware State Register use

Hi,

The FSR (Firmware State Register) holds the ROM state information, it does not
contain error information.
The FSR itself is a bit more complicated as well as the state depends on the
module currently in use.

The error code from ROM or the status code from the firmware is located at the
next register.

Fix the handling of the FSR in order to provide usable and human readable (in
most cases) report on the status and error.

Regards,
Peter
