Hi Umang,

Drop custom logging from the vchiq_core.c and use standard kernel
logging infrastructure (dev_dbg() and friends for struct Device
stuff) and pr_info (and similar) for vchiq_services/instances things.
i'm sorry but your "staging: vc04_services: vchiq: Register devices with a custom bus_type" is still in my backlog. I was busy with some regressions on bcm2835/bcm2711.

Some log levels like this here doesn't make sense. I would expect here a warning or an error. Could you please have look at it in a separate patch?

Thanks
