ALSA: hda - Fix silent speaker output due to mute LED fixup
commit 415d555e6b398b00fc1733f0113065a54df9106a upstream. The recent fixups for HP laptops to support the mute LED made the speaker output silent on some machines. It turned out that they use the NID 0x18 for the speaker while it's also used for controlling the LED via VREF bits although the current driver code blindly assumes that such a node is a mic pin (where 0x18 is usually so). This patch fixes the problem by only changing the VREF bits and keeping the other pin ctl bits.
