Subject: kbuild: make sure autoksyms.h exists early
X-Git-Tag: v4.9-rc8~13
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d3fc425e819be7c251a9c208cd4c0a6373c19bfe;p=karo-tx-linux.git

kbuild: make sure autoksyms.h exists early

Some people are able to trigger a race where autoksyms.h is used before
its empty version is even created.  Let's create it at the same time as
the directory holding it is created.
