[PATCH v2 01/13] initramfs: replace klibcdirs in Makefile with FORCE

From: Masahiro Yamada
Date: Sat Jan 04 2020 - 10:03:57 EST


'klibcdirs' was added by commit d39a206bc35d ("kbuild: rebuild initramfs
if content of initramfs changes"). If this is just a matter of forcing
execution of the recipe line, we can replace it with FORCE.

I do not understand the purpose of

$(deps_initramfs): klibcdirs

Remove it.
