Subject: [PATCH 03/17] apparmor: Fix an error code in aafs_create()
References: FATE#323500
Patch-mainline: v4.14-rc2
Git-commit: 5d314a81eca29b01939930c1c596dfa44937e970
We accidentally forgot to set the error code on this path. It means we
return NULL instead of an error pointer. I looked through a bunch of
callers and I don't think it really causes a big issue, but the
documentation says we're supposed to return error pointers here.
