[PATCH] ASoC: meson: implement driver_name for snd_soc_card in meson-card-utils

[Christian Hewitt]

Implement driver_name to provide an alternative to card_name for userspace
configuration of Amlogic audio cards.

The meson AIU/AXG drivers currently require alsa confs based on the board
model name which is unique to each board. This is very flexible for audio
use-cases, but not very maintainable for distros with a single use-case
that need to support a large number of different Amlogic boards. Using a
driver name to match the card conf instead of card/model name reduces the
number of confs needed in the LibreELEC (Kodi) distro from 41 to 2.

I was preparing something similar to help with alsa-ucm so

Thanks!

[1/1] ASoC: meson: implement driver_name for snd_soc_card in meson-card-utils
      commit: bc387887ae22d6ed6439e83968b5be3443a8e57d

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
