| H A D | Makefile.include | diff c2bd08ba20a57e0ed55777a9d1724647a0f53e88 Wed Feb 21 14:42:01 CET 2024 Masahiro Yamada <masahiroy@kernel.org> treewide: remove meaningless assignments in Makefiles
In Makefiles, $(error ), $(warning ), and $(info ) expand to the empty
string, as explained in the GNU Make manual [1]:
"The result of the expansion of this function is the empty string."
Therefore, they are no-op except for logging purposes.
$(shell ...) expands to the output of the command. It expands to the
empty string when the command does not print anything to stdout.
Hence, $(shell mkdir ...) is no-op except for creating the directory.
Remove meaningless assignments.
