Subject: [PATCH 4.14 58/70] platform/x86: fix kconfig dependency warning for FUJITSU_LAPTOP

From: Necip Fazil Yildiran <fazilyildiran@...il.com>

[ Upstream commit afdd1ebb72051e8b6b83c4d7dc542a9be0e1352d ]

When FUJITSU_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]:
  - FUJITSU_LAPTOP [=y] && X86 [=y] && X86_PLATFORM_DEVICES [=y] && ACPI [=y] && INPUT [=y] && BACKLIGHT_CLASS_DEVICE [=y] && (ACPI_VIDEO [=n] || ACPI_VIDEO [=n]=n)

The reason is that FUJITSU_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.
