cfg80211: off by one in ieee80211_bss()
We do a: sprintf(buf, " Last beacon: %ums ago", elapsed_jiffies_msecs(bss->ts)); elapsed_jiffies_msecs() can return a 10 digit number so "buf" needs to be 31 characters long. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
