From 908e5a3d4e6f60fa2d3912be7087e745639c4404 Mon Sep 17 00:00:00 2001 From: Minjie Du Date: Tue, 25 Jul 2023 11:50:37 +0800 Subject: [PATCH] spi: fsl-dspi: Use dev_err_probe() in dspi_request_dma() It is possible for dma_request_chan() to return EPROBE_DEFER, which means dev is not ready yet. At this point dev_err() will have no output.
