v3:
 - Restored Frank's Reviewed-by tag from v1 (Adrian).
 - Formatted platform_device_id entry with '{' on a separate line (Adrian).
 - Moved amd_pt_info definition to match device table order (Adrian).
 - Added space before closing brace in mipi_i3c_hci_pci_devices[] (Adrian).
 - Aligned From: and Signed-off-by: email addresses (Adrian).
v2:
 - No changes (rebased on top of v2 patch series).
