The proper pointer to be passed as argument to PTR_ERR() is priv->icc_pdev. This bug was detected with the help of Coccinelle.

Instead of adding a virtual one just make the main &noc act as the global interconnect provider. The imx interconnect provider driver will scale the NOC and DDRC based on bandwidth request. More scalable nodes can be added in the future, for example for audio/display/vpu/gpu NICs.

All this driver does is set a clk rate based on an opp table, it does not map register areas.
