The commit 71f642833284 ("ACPI: utils: Fix reference counting in for_each_acpi_dev_match()") moved adev assignment outside of error path and hence made acpi_dev_put(sensor->adev) a no-op. We still need to drop reference count on error path, and to achieve that, replace sensor->adev by locally assigned adev.
