6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Smita Koralahalli <Smita.KoralahalliChannabasappa@amd.com>

[ Upstream commit 84973331442a57bac31b40eaef6f264496c6f3fd ]

Rename the protocol error struct from struct cper_sec_prot_err to
struct cxl_cper_sec_prot_err and cper_print_prot_err() to
cxl_cper_print_prot_err() to maintain naming consistency. No
functional changes.
