Subject: [PATCH 127/247] regulator: core: validate selector against
|
|
linear_min_sel
|
|
|
|
There are regulators who's min selector is not zero. Selectors loops
|
|
(looping b/w zero and regulator::desc::n_voltages) might throw errors
|
|
because invalid selectors are used (lower than
|
|
regulator::desc::linear_min_sel). For this situations validate selectors
|
|
against regulator::desc::linear_min_sel.
