No worries - I just want to merge code that is actually used, I assume
the series above should be reposted right ? You need an ACK from Thierry
for it and we can merge the whole thing on top of Kishon's patches.
I was just referring to the wrapper above, it does not seem very
useful given that we can call pci_epc_init_notify() directly,
please correct me if I am wrong, there does not seem to be anything
DWC specific (at least for the time being) in the _notify() hook.
