Subject: [PATCH v2 2/2] media: imx-media-csi: Do not propagate the error when pinctrl is not found
Date: Sat,  3 Mar 2018 08:47:15 -0300	[thread overview]
Message-ID: <1520077635-21464-2-git-send-email-festevam@gmail.com> (raw)
In-Reply-To: <1520077635-21464-1-git-send-email-festevam@gmail.com>

From: Fabio Estevam <fabio.estevam@nxp.com>

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.
