OK, so how can I solve the fact that we have one clock that is gotten with clk_get_sys()? The priv-pointer was reused for the delay in the regulator-supply, so I assumed that it was ok here as well. How should I do it so that it is OK with you, then?

+int snd_soc_dapm_get_power_status(struct snd_soc_dapm_context *dapm,
const char *pin)This appears to be *nothing* to do with the rest of the patch! It's also not clear what it's for.
It is for the debugging in our driver, using it to get the status of our clocks so that we can make sure that the correct clocks are enabled/disabled at certain points that we find useful. I named it get_power_status instead of get_clock_status, just because I thought you would complain that get_clock_status was using the ->power, which is not specific to just clock-widgets.
