[PATCH 2/2] mfd: stmfx: Nullify stmfx->vdd in case of error

From: Amelie Delaunay
Date: Thu Mar 16 2023 - 12:54:25 EST


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()")
