NULL check on clocks obtained using common clock APIs should not

I think this patch is incomplete. You need to ensure all the clock pointers
are initially set to an invalid value. This is currently done with
memsetting
whole hdmi_resource structure to 0. But now some ERR_PTR() value needs to be
used instead. Same applies to your subsequent patch.
Thanks,
Sylwester
