Subject: [PATCH v2 3/5] media: nxp: imx8-isi: use devm_pm_runtime_enable() to simplify code
Date: Wed, 19 Nov 2025 16:34:26 -0500	[thread overview]
Message-ID: <20251119-cam_cleanup-v2-3-df732cc83ff1@nxp.com> (raw)
In-Reply-To: <20251119-cam_cleanup-v2-0-df732cc83ff1@nxp.com>

Use devm_pm_runtime_enable() to simplify code. Change to use
dev_err_probe() because previous goto change to return.

No functional change.

Signed-off-by: Frank Li <Frank.Li@nxp.com>

change in v2
- remove error code print at dev_err_probe.
