Subject: mfd: use the value of the final spin when reading the AUXADC
From: Mark Brown <broonie@xxxxxxxxxxxxxxxxxxxxxxxxxxx>
Reverse the order of the tests for loop exit so we use a valid value
before we time out. Vanishingly unlikely to happen since we retry for
several times the expected conversion time.
