[alsa-devel] [PATCH RESEND] ASoC: kirkwood: prefer external clock over internal clock

[Jean-Francois Moine]

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.

This patch was initialy proposed by Russell, but with an erroneous
'else if'.
