This depends on the version of GNU Make. The warning is displayed if you use GNU Make 4.1 or older. No more annoying warning is displayed for GNU Make 4.2 or later. Probably, this commit in GNU Make: commit 87a5f98d248fe63fe6e3e53ee3e1b1b1fa5e49dc Author: Paul Smith <psmith@xxxxxxx> Date: Sat Apr 9 19:49:27 2016 -0400 [SV 102] Don't show unnecessary include file errors. However, 4.2 is quite new. I will do something with it. Thanks. > drivers/staging/mt7621-dts/Kconfig:4:warning: 'BUILTIN_DTB' has wrong type.
