Subject[PATCH AUTOSEL 5.2 10/85] soc: imx: soc-imx8: Correct return value of error handle
Date
From: Anson Huang <Anson.Huang@nxp.com>

[ Upstream commit 4c396a604a57da8f883a8b3368d83181680d6907 ]

Current implementation of i.MX8 SoC driver returns -ENODEV
for all cases of error during initialization, this is incorrect.
This patch fixes them using correct return value according
to different errors.
