So, I just looked at that driver - it errors out on probe without the regualtor. Are you sure the fix isn't to add a dependency on the regulator API or convert it back to using normal regulator gets (it was converted without comment as part of a DT conversion), or indeed to using the bulk regulator API. It looks awfully like the driver is just open coding devm_regulator_bulk_get() and friends.
There is no explanation at all in either the changelog or the code for why the driver is asking for exclusive regulators. [unhandled content-type:application/pgp-signature] | |
