Hi,

When LG_LAPTOP is enabled and NEW_LEDS is disabled, it results in the
following Kbuild warning:

WARNING: unmet direct dependencies detected for LEDS_CLASS
Depends on [n]: NEW_LEDS [=n]
Selected by [y]:
- LG_LAPTOP [=y] && X86 [=y] && X86_PLATFORM_DEVICES [=y] && ACPI [=y] && ACPI_WMI [=y] && INPUT [=y]

The reason is that LG_LAPTOP selects LEDS_CLASS without depending on or
selecting NEW_LEDS while LEDS_CLASS is subordinate to NEW_LEDS.

Honor the kconfig menu hierarchy to remove kconfig dependency warnings.

Thnak you, patch looks good to me:

Note it seems that the FUJITSU_LAPTOP Kconfig symbol has the same
issue, can you submit a patch for that one too?

Regards,

Hans
