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