Subject: cfg80211: make certificate generation more robust
From: Johannes Berg <johannes.berg@xxxxxxxxx>
commit b5642479b0f7168fe16d156913533fe65ab4f8d5 upstream.
If all net/wireless/certs/*.hex files are deleted, the build
will hang at this point since the 'cat' command will have no
arguments. Do "echo | cat - ..." so that even if the "..."
part is empty, the whole thing won't hang.
