Subject: ASoC: rt298: Add DMI match for Broxton-P reference platform
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b9c17f13ba484d8492278c67cd95b7207def776f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ASoC: rt298: Add DMI match for Broxton-P reference platform

Broxton-P reference platform also uses combo jack for audio
connector so we need to set codec pdata to use this based on DMI
match for this board.
