[PATCH v2] ASoC: meson: fixes the missed kfree() for axg_card_add_tdm_loopback

[Jing Xiangfeng]

axg_card_add_tdm_loopback() misses to call kfree() in an error path. We
can use devm_kasprintf() to fix the issue, also improve maintainability.
So use it instead.

Thanks!

[1/1] ASoC: meson: fixes the missed kfree() for axg_card_add_tdm_loopback
      commit: bd054ece7d9cdd88e900df6625e951a01d9f655e

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
