6.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Srinivas Pandruvada <srinivas.pandruvada@xxxxxxxxxxxxxxx>
[ Upstream commit 57221a07ff37ff356f9265acd228bc3c8744c8fc ]
The vsec offset can be 64 bit long depending on the PFS start. So change
type to u64. Also use 64 bit formatting for seq_printf.
Fixes: 47731fd2865f ("platform/x86/intel: Intel TPMI enumeration driver")
