Subject: [PATCH] ata: pata_pxa: convert not to use dma_request_slave_channel()
Date: Sun, 12 Nov 2023 16:07:59 +0100 [thread overview]
Message-ID: <f177835b7f0db810a132916c8a281bbdaf47f9d3.1699801657.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.
