Subject: [PATCH] ALSA: hda/realtek - Fix the problem of the front MIC on the Lenovo M715

Git-commit: d06fb562bff5d14defdacbd92449bacbaedd5cdf

Patch-mainline: v4.20-rc1

References: bsc#1051510

The front MIC on the Lenovo M715 can't record sound, after applying

the ALC294_FIXUP_LENOVO_MIC_LOCATION, the problem is fixed. So add

the pin configuration of this machine to the pin quirk table.
