    Subject[PATCH 4.20 050/171] platform/x86: Fix unmet dependency warning for ACPI_CMPC
    Date
    4.20-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    [ Upstream commit d58bf90a32a33becec78c3034e781735049fcd25 ]

    Add BACKLIGHT_LCD_SUPPORT for ACPI_CMPC to fix the
    warning: unmet direct dependencies detected for BACKLIGHT_CLASS_DEVICE.

    ACPI_CMPC selects BACKLIGHT_CLASS_DEVICE but BACKLIGHT_CLASS_DEVICE
    depends on BACKLIGHT_LCD_SUPPORT.

    Copy BACKLIGHT_LCD_SUPPORT dependency into ACPI_CMPC to fix

    WARNING: unmet direct dependencies detected for BACKLIGHT_CLASS_DEVICE
    Depends on [n]: HAS_IOMEM [=y] && BACKLIGHT_LCD_SUPPORT [=n]
    Selected by [y]:
    - ACPI_CMPC [=y] && X86 [=y] && X86_PLATFORM_DEVICES [=y] && ACPI [=y] && INPUT [=y] && (RFKILL [=n] || RFKILL [=n]=n)
