4.19-stable review patch. If anyone has any objections, please let me know.
------------------ From: Larry Finger <[email protected]> commit 8cfa272b0d321160ebb5b45073e39ef0a6ad73f2 upstream. With commit 0a9f8f0a1ba9 ("rtlwifi: fix btmpinfo timeout while processing C2H_BT_INFO"), calling rtl_c2hcmd_enqueue() with rtl_c2h_fast_cmd() true, the routine returns without freeing that skb, thereby leaking it. This issue has been discussed at https://github.com/lwfinger/rtlwifi_new/issues/401 and the fix tested there.
