4 Subject: [PATCH] regulator_get_optional: don't print an error when no
5 regulator is found
6
7 Only print an error when _regulator_get() is expected to return a valid
8 regulator, that is when _regulator_get() is called from regulator_get() and
9 we're not using the dummy because we don't have full-constraints, or when
10 _regulator_get() is called from regulator_get_exclusive() in which case
11 returning a dummy is not allowed.
