[PATCH 5.15 141/164] drivers: iio: mpu3050: use dev_err_probe for regulator request

[ Upstream commit b010880b9936da14f8035585ab57577aa05be23a ]

Regulator requesting may result in deferred probing error which will
abort driver probing. To avoid this just use dev_err_probe which handles
deferred probing.
