Merge series "ASoC: SOF: small fixes for 5.10" from Kai Vehmanen <kai.vehmanen@linux.intel.com>:

Series that adds debug support for IMX platforms, more details to
FW version information, adds missing -EACCESS handling to
pm_runtime_get_sync() calls and a set of minor cosmetic, trace
verbosity and coding style issues.

Guennadi Liakhovetski (3):
  ASoC: SOF: (cosmetic) remove redundant "ret" variable uses
  ASoC: SOF: remove several superfluous type-casts
  ASoC: SOF: fix range checks

Iulian Olaru (1):
  ASoC: SOF: imx: Add debug support for imx platforms

Karol Trzcinski (1):
  ASoC: SOF: Add `src_hash` to `sof_ipc_fw_version` structure

Pierre-Louis Bossart (3):
  ASoC: SOF: debug: update test for pm_runtime_get_sync()
  ASoC: SOF: control: update test for pm_runtime_get_sync()
  ASoC: SOF: Intel: hda: reduce verbosity of boot error logs
