When we plug a micrphone into it, the system can't detect this microphone and can't record sound via this microphone too. [Fix] Apply the quirk of ALC294_FIXUP_LENOVO_MIC_LOCATION, the alsa driver will assign a different name to this audio jack, then pulseaudio can handle this jack and everything works well. [Test Case] plug a microphone to this jack and record sound, system can detect the microphone and can record sound. [Regression Potential] Very low, this pin configuration is specific to the machine of M715 so far, will not affect other machines.
