No, don't think so.
I think that calling mclk_get_divisor() too early, when
pcdev->soc_host.dev is not set, is the issue here (dev_warn is
mclk_get_divisor()).
And for the same price, I'll give you another stack :)
I'll leave that one up to you, as I'm not really confortable with that type of
sequence :
if (!icd->dev.parent ||
to_soc_camera_host(icd->dev.parent)->nr != icd->iface)
