[PATCH RFT] regulator: qcom_smd: Remove list_voltage callback for rpm_smps_ldo_ops_fixed

[Axel Lin]

Use regulator_list_voltage_linear_range in rpm_smps_ldo_ops_fixed is
wrong because it is used for fixed regulator without any linear range.
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.

TBH, 3bfbb4d1a480 patch was never in the mailing list, am sure there is 
some confusion while applying other patches.

May be a8a47540ebe3 got re-applied, without any errors/warning I guess.

These are the only 2 patches which were submitted in mailing list and 
which made into next.

Applied "regulator: qcom_smd: Remove list_voltage callback for rpm_smps_ldo_ops_fixed" to the regulator tree

[Mark Brown]

The patch

   regulator: qcom_smd: Remove list_voltage callback for rpm_smps_ldo_ops_fixed

has been applied to the regulator tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] regulator: qcom_smd: Remove list_voltage callback for
 rpm_smps_ldo_ops_fixed

Use regulator_list_voltage_linear_range in rpm_smps_ldo_ops_fixed is
wrong because it is used for fixed regulator without any linear range.
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.
