Subject: [PATCH 5.15 235/667] media: i2c: max9286: Use dev_err_probe() helper

From: Niklas Söderlund <niklas.soderlund+renesas@...natech.se>

[ Upstream commit df78b858e773967112b4444400fb7bb5bd7a9d8a ]

Use the dev_err_probe() helper, instead of open-coding the same
operation. While at it retrieve the error once and use it from
'ret' instead of retrieving it twice.
