Subject: [PATCH] ASoC: tegra: convert not to use dma_request_slave_channel()
Date: Sat, 11 Nov 2023 18:37:39 +0100	[thread overview]
Message-ID: <b78685e4103f12931ddb09c1654bc6b04b640868.1699724240.git.christophe.jaillet@wanadoo.fr> (raw)

dma_request_slave_channel() is deprecated. dma_request_chan() should
be used directly instead.

Switch to the preferred function and update the error handling accordingly.
