_opp_supported_by_regulators() wrongly ignored errors from
regulator_is_supported_voltage(), so it considered errors as
success. Since
commit 498209445124 ("regulator: core: simplify return value on suported_voltage")
regulator_is_supported_voltage() returns a real boolean, so
errors make _opp_supported_by_regulators() return false.
That reveals a problem with the declaration of the VDD1/2
regulators on twl4030.
The VDD1/VDD2 regulators on twl4030 are neither defined with
voltage lists nor with the continuous flag set, so
regulator_is_supported_voltage() returns false and an error
before above mentioned commit (which was considered success)
The result is that after the above mentioned commit cpufreq
does not work properly e.g. dm3730.

The patch
regulator: twl: voltage lists for vdd1/2 on twl4030
has been applied to the regulator tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-5.3
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: twl: voltage lists for vdd1/2 on twl4030
_opp_supported_by_regulators() wrongly ignored errors from
regulator_is_supported_voltage(), so it considered errors as
success. Since
commit 498209445124 ("regulator: core: simplify return value on suported_voltage")
regulator_is_supported_voltage() returns a real boolean, so
errors make _opp_supported_by_regulators() return false.
That reveals a problem with the declaration of the VDD1/2
regulators on twl4030.
The VDD1/VDD2 regulators on twl4030 are neither defined with
voltage lists nor with the continuous flag set, so
regulator_is_supported_voltage() returns false and an error
before above mentioned commit (which was considered success)
The result is that after the above mentioned commit cpufreq
does not work properly e.g. dm3730.

I am not sure who the right maintainer is, but as of today, cpufreq
for users of twl4030 on 5.3-RC8 is still broken without this patch.
Is there any way it can be applied before the final release?
