cfg80211: make certificate generation more robust
commit b5642479 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. Cc: stable@vger.kernel.org Signed-off-by:Johannes Berg <johannes.berg@intel.com> Signed-off-by:
