Subject: [PATCH 06/10] perf hisi-ptt: Extract the raw data printing part

From: Sizhe Liu <[email-masked]>
Date: Thu, 4 Jun 2026 15:50:01 +0800

Extract the raw data printing part of the TLP header into
hisi_ptt_print_raw_record() for reuse by subsequent patches that
add field-level parsing of individual DW headers.
