Subject: [PATCH] ALSA: hda/realtek: Fix headset mic on ASUS Zenbook 14
UX3402VA

The UX3402VA (1043:16a3) BIOS leaves pin 0x19 unconfigured, so the headset mic does not work. Use ALC294_FIXUP_ASUS_SPI_HEADSET_MIC like the UX3405MA, it sets up the mic and keeps the CS35L41 speaker fixup.

Tested on a UX3402VA: headset mic, internal mic and speakers work.
