Cong Wang d5c7c745f2 net/wan: fix a double free in x25_asy_open_tty() ... When x25_asy_open() fails, it already cleans up by itself, so its caller doesn't need to free the memory again. It seems we still have to call x25_asy_free() to clear the SLF_INUSE bit, so just set these pointers to NULL after kfree().
