Subject: [PATCH] i2c: mxs: suppress probe-deferral error message
Date: Sat, 7 Jan 2023 13:32:29 +0100 [thread overview]
Message-ID: <20230107123229.4218-1-stefan.wahren@i2se.com> (raw)
During boot of I2SE Duckbill the kernel log contains a
confusing error:
Failed to request dma
This is caused by i2c-mxs tries to request a not yet available DMA
channel (-EPROBE_DEFER). So suppress this message by using
dev_err_probe().
