[PATCH 0/4] ipmi: Allow dynamic device IDs

This series implements a more dynamic method of reporting BMC version & identification. The current method of registering versions and IDs during ipmi_register_smi means that if a BMC is upgraded during a boot, the IPMI core code will report old version information. We do this by querying the BMC

Currently, it's up to the IPMI SMIs to provide the product & version details of BMCs behind registered IPMI SMI interfaces. This device ID is provided on SMI regsitration, and kept around for all future queries. However, this version information isn't always static. For example, a BMC may be
