Subject: [PATCH] thunderbolt, efi: Fix Kconfig dependencies
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Fix this EFI build failure on certain (rand)configs:

  drivers/firmware/efi/apple-properties.c:149:9: error: implicit declaration of function ???efi_get_device_by_path??? [-Werror=implicit-function-declaration]

which is due to:

  warning: (THUNDERBOLT) selects APPLE_PROPERTIES which has unmet direct dependencies (EFI && EFI_STUB && X86)
