Hi Sven,
Subject: [PATCH] regulator: Allow autosetting fixed regulators
Fixed regulators don't have a set_value method. Therefore, regulator_set_value will return -ENOSYS when called from regulator_autoset.
Accepting this return value allows autosetting fixed regulators.

- if (!ret)
- if (!ret || ret == -ENOSYS)
According to code: if (uc_pdata->flags & REGULATOR_FLAG_AUTOSET_UV) ret = regulator_set_value(dev, uc_pdata->min_uV); if (!ret && (uc_pdata->flags & REGULATOR_FLAG_AUTOSET_UA)) ret = regulator_set_current(dev, uc_pdata->min_uA);
So you get -ENOSYS from the upper code?
Regards, Peng.
ret = regulator_set_enable(dev, true);return ret;
