Subject: kbuild: fix make TAGS (for emacs use)
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=66d609ec8a4464b5fbe7a0723e3958b98c95991a;p=linux-beck.git

kbuild: fix make TAGS (for emacs use)

From: bongiojp@clarkson.edu <Jeremy Bongio>
make TAGS does not make source code tags for emacs. It instead
returns an error than "etags -" isn't valid. The problem is
easily remedied.
