Subject: [PATCH 4.14 007/140] ASoC: Intel: Skylake: Fix jack name format substitution

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chintan Patel <chintan.m.patel@...el.com>

commit d1c4cb447a7efcb5608a33cdfed8ab4234378b0a upstream.

Jack name is not getting formatted correctly hence resulting
in invalid name for HDMI/DP input devices.

This was recently exposed due changes brought by MST:
commit 3a13347f05fd ("ASoC: Intel: kbl: Add jack port initialize
in kbl machine drivers")
