Commit Message

David E. Box Nov. 29, 2023, 10:21 p.m. UTC 
The PMT header is passed to several functions. Instead, store the header in
struct intel_pmt_entry which is also passed to these functions and shorten
the argument list. This simplifies the calls in preparation for later
changes. While here also perform a newline cleanup.
