Subject: [PATCH v3 1/3] Bluetooth: btintel_pcie: Print Firmware Sequencer information
Date: Fri, 17 May 2024 15:24:45 +0530
Message-Id: <20240517095447.956132-1-kiran.k@intel.com>

Firmware sequencer (FSEQ) is a common code shared across Bluetooth
and Wifi. Printing FSEQ will help to debug if there is any mismatch
between Bluetooth and Wifi FSEQ.

Make 'btintel_print_fseq_info' public and use it in btintel_pcie.c.

dmesg:
