3.2-stable review patch. If anyone has any objections, please let me know. ------------------ From: Takashi Iwai <redacted> commit ca3649de026ff95c6f2847e8d096cf2f411c02b3 upstream. Some output pins on Conexant chips have no HP control bit, but the auto-parser initializes these pins unconditionally with PIN_HP. Check the pin-capability and avoid the HP bit if not supported.
