[PATCH V6 09/20] platform/x86/intel/pmt: Add header to struct intel_pmt_entry

David E. Box
2023-11-29T22:22:15Z

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.
