memcpy() call with "idata == NULL && ilen == 0" results in undefined behavior in ar5523_cmd(). For example, NULL is passed in callchain "ar5523_stat_work() -> ar5523_cmd_write() -> ar5523_cmd()". This patch adds ilen check before memcpy() call in ar5523_cmd() to prevent an undefined behavior. Cc: Pontus Fuchs <pontus.fuchs@gmail.com> Cc: Kalle Valo <kvalo@codeaurora.org> Cc: "David S.
