Subject[PATCH 3/6] ipmi: msghandler: Add and use pr_fmt and dev_fmt, remove PFX
Date
Standardize the prefixing of output messages using the pr_fmt and dev_fmt
mechanisms instead of a separate #define PFX

Miscellanea:

o Because this message prefix is very long, use a non-standard define
of #define pr_fmt(fmt) "%s" fmt, "IPMI message handler: "
which removes ~170 bytes of object code in an x86-64 defconfig with ipmi
(with even more object code reduction on 32 bit compilations)
