PCI hotplug: pciehp: message refinement
Browse files Browse the repository at this point in the history 
This patch refines messages in pciehp module.  The main changes are as
follows:

 - remove the trailing "."
 - remove __func__ as much as possible
 - capitalize the first letter of messages
 - show PCI device address including its domain
