4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Takashi Iwai <[email protected]> commit c288248f5b26cd5563112fcdc077bf44964a942d upstream. hdmi_lpe_audio_probe() copies the pcm name string via strncpy(), but as a gcc8 warning suggests, it misses a NUL terminator, and unlikely the expected result. Use the proper one, strlcpy() instead.
