The first error path (ieee80211_tx_prepare() returning\nTX_DROP) does not free it, while invoke_tx_handlers() failure and the\nfragmentation check both do.\n\nAdd kfree_skb() to the first error path so all three are consistent,\nand remove the now-redundant frees in callers (ath9k, mt76,\nmac80211_hwsim) to avoid double-free.\n\nDocument the skb ownership guarantee in the function's kdoc.",
