Here is the issue of entering into the subdir twice if both
options are enabled again (and also the indent is wrong
and seems to be using spaces).
I've fixed this by adding making some changes to:
drivers/platform/x86/intel/atomisp2/Kconfig
I added:
config INTEL_ATOMISP2_PDX86
bool
Which is basically a hidden (not user selectable) bool option,
defaulting to N (which is the default default)
And then I added:
select INTEL_ATOMISP2_PDX86
The the config bits for both CONFIG_INTEL_ATOMISP2_LED and CONFIG_INTEL_ATOMISP2_PM
and then used the new CONFIG_INTEL_ATOMISP2_PDX86 in the Makefile to dive into
the subdir.
I have made these changes while merging the series there is no need for
a new version.
Regards,
Hans
