[PATCH 2/6] ASoC: sunxi: sun4i-codec: Drop redundant error messages

[Bui Duc Phuc]

Hi all,

Actually, following our discussion about dma_request_chan() not always
printing error logs internally, I did some further investigation into
the code paths and have submitted two patches to address the underlying
issues more comprehensively:

1. A patch for dma_request_chan() itself to prevent potential NULL pointer
   dereferences on invalid arguments:
   https://lore.kernel.org/all/20260716052758.23465-1-phucduc.bui@gmail.com/

2. A patch to improve the error handling flow inside
   dmaengine_pcm_request_chan_of() when calling dma_request_chan():
   https://lore.kernel.org/all/20260716080428.57979-1-phucduc.bui@gmail.com/

I wanted to share this here to provide more context on the proposed changes to
these DMA engine error-handling flows.

Best regards,
Phuc
