ALSA: hda - Fix silent headphone output on Panasonic CF-74
CF-74 does the headphone/speaker switching on hardware, thus the driver shouldn't do any software-toggling of pins. Otherwise it results in a silent headphone output. This patch simply resets the hp_detect flag to fix the problem. Signed-off-by: Takashi Iwai <tiwai@suse.de>
