Re: [PATCH v3] ASoC: soc-generic-dmaengine: Handle DMA channel request failures correctly

[Sebastian Reichel]

Hi,

The new warning triggers for the Rockchip SPDIF driver [0], which
is playback only and thus only has a 'tx' DMA channel:

[    2.275100] rockchip-spdif 27ea0000.spdif-tx: DTS/ACPI name 'rx' not found, legacy failed (-19)

This is from RK3576 Sige5, which does not yet have the node enabled
upstream. But it should be exactly the same for any RK3576, RK3588
or RK3568 board at least.

[0] sound/soc/rockchip/rockchip_spdif.c

Greetings,

-- Sebastian
