From f1c7f92ee9ec38aa5e6526257a8a9f1fffc52511 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sun, 19 Nov 2023 19:00:58 +0100 Subject: [PATCH] serial: sh-sci: 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.
