Subject: ASoC: kirkwood: prefer external clock over internal clock
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1f1b65796ef882bb9101d22b17e1a1824b3a6489;p=linux-beck.git

ASoC: kirkwood: prefer external clock over internal clock

When there is an external clock, always use this one.
This prevents the two Dove audio devices to use the same DCO clock
at different rates.
