[PATCH 1/2] ARM: kirkwood: fix a not initialized variable in the sound subsystem

[moinejf@free.fr (Jean-Francois Moine)]

In the function kirkwood_set_rate, in case of a non dco supported rate
and no external clock, the clock source was set to an undefined value.
This patch just displays a message without changing the clock source.
