| Subject: mfd: stmfx: Nullify stmfx->vdd in case of error |
| |
| From: Amelie Delaunay <amelie.delaunay@foss.st.com> |
| |
| [ Upstream commit 7c81582c0bccb4757186176f0ee12834597066ad ] |
| |
| Nullify stmfx->vdd in case devm_regulator_get_optional() returns an error. |
| And simplify code by returning an error only if return code is not -ENODEV, |
| which means there is no vdd regulator and it is not an issue. |
| |
| Fixes: d75846ed08e6 ("mfd: stmfx: Fix dev_err_probe() call in stmfx_chip_init()") |
