Subject: [PATCH V5 08/20] platform/x86/intel/pmt: Add header to struct intel_pmt_entry
Date: Wed, 22 Nov 2023 20:03:43 -0800	[thread overview]
Message-ID: <20231123040355.82139-9-david.e.box@linux.intel.com> (raw)
In-Reply-To: <20231123040355.82139-1-david.e.box@linux.intel.com>

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.

Signed-off-by: David E. Box <david.e.box@linux.intel.com>
