+description:
+ The TAS2781 is a mono, digital input Class-D audio amplifier
+ optimized for efficiently driving high peak power into small
+ loudspeakers. An integrated on-chip DSP supports Texas Instruments
+ Smart Amp speaker protection algorithm. The integrated speaker
+ voltage and current sense provides for real time

Changes in v6:
- fixed issue | Reported-by: kernel test robot <[email protected]>
| Link: https://lore.kernel.org/oe-kbuild-all/[email protected]/
- Move back to codecs folder, this firmware lib is special for the audio cases
- | Reported-by: kernel test robot <[email protected]>
| Closes: https://lore.kernel.org/oe-kbuild-all/[email protected]/
- change enum channel to unsigned short
- coding style correction
- fixed active_device detection issue in different configs in tasdevice_add_config.
- fixed the log output level from dev_info to dev_err at error branch
in tas2781_load_calibration
- correct the conf_no boundary in tasdevice_select_tuningprm_cfg
- add force firmward load status in tasdevice_select_tuningprm_cfg
- "Unneeded loading dsp conf" as the non-error

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
