[PATCH v2] regulator: Kconfig: Fix REGULATOR_QCOM_RPMH dependencies to avoid build error

[John Stultz]

The kernel test robot reported the following build error:

All errors (new ones prefixed by >>):

   xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_vrm_get_voltage_sel':
   qcom-rpmh-regulator.c:(.text+0x270): undefined reference to `rpmh_write'
   xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_send_request':
   qcom-rpmh-regulator.c:(.text+0x2f2): undefined reference to `rpmh_write'
   xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_vrm_get_voltage_sel':
>> qcom-rpmh-regulator.c:(.text+0x274): undefined reference to `rpmh_write_async'
   xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_send_request':
   qcom-rpmh-regulator.c:(.text+0x2fc): undefined reference to `rpmh_write_async'

Which is due to REGULATOR_QCOM_RPMH depending on
QCOM_RPMH || COMPILE_TEST. The problem is that QOM_RPMH can now
be a module, which in that case requires REGULATOR_QCOM_RPMH=m
to build.

However, if COMPILE_TEST is enabled, REGULATOR_QCOM_RPMH can be
set to =y while QCOM_RPMH=m which will cause build failures.

The fix here is to add (QCOM_RPMH=n && COMPILE_TEST) to the
dependency.

Feedback would be appreciated!

[1/1] regulator: Kconfig: Fix REGULATOR_QCOM_RPMH dependencies to avoid build error
      commit: 34c5aa2666db54c4bd330fb2759f6e4d4544ad7a

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
