Subject: media: imx-media-csi: Do not propagate the error when pinctrl is not
found
Author: Fabio Estevam <fabio.este...@nxp.com>
Date: Sat Mar 3 07:56:30 2018 -0500
Since commit 52e17089d185 ("media: imx: Don't initialize vars that
won't be used") imx_csi_probe() fails to probe after propagating the
devm_pinctrl_get_select_default() error.
devm_pinctrl_get_select_default() may return -ENODEV when the CSI pinctrl
entry is not found, so better not to propagate the error in the -ENODEV
case to avoid a regression.
