It has been in -next for a while, the issues in mainline for these platforms weren't flagged up to me until yesterday (I think it took some time to figure out what was going wrong)" * tag 'qcom-smd-list-voltage' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: regulator: qcom_smd: Remove list_voltage callback for rpm_smps_ldo_ops_fixed 2016-07-01T16:06:48Z Mark Brown broonie@kernel.org 2016-07-01T16:06:48Z urn:sha1:a29a36f2650dbaa54c8aed8cc9af909113c19ad3 2016-06-29T17:50:05Z Venkat Reddy Talla vreddytalla@nvidia.com 2016-06-29T10:01:27Z urn:sha1:91ff811f32763ea3135e832f7c1aeafc85ae1c98 SD4 regulator is not registered with regulator core framework in probe as there is no support in MAX77620 PMIC, removing SD4 entry from MAX77620 regulator information list and checking for valid regulator information data before configuring FPS source and FPS power up/down period to avoid NULL pointer exception if regulator not registered with core.

A check for valid voltage selectors was added in commit da0607c8df5c ("regulator: anatop: Fail on invalid voltage selector") but it also discards all regulators that are in bypass mode. Add check for the bypass setting.

The rpm_smps_ldo_ops_fixed is used for pm8941_lnldo which has fixed_uV set and n_voltages = 1. In this case, regulator_list_voltage() can return rdev->desc->fixed_uV without .list_voltage implementation.
