From 804901fdd637c7af8b767c329fd84aa0d3d617ec Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 18 Nov 2023 09:42:07 +0100 Subject: ata: pata_pxa: convert not to use dma_request_slave_channel() 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. While at it, also propagate the error code that is now available.
