Box" [ Upstream commit 9577c74c96f88d807d1ba005adbf5952e7127e55 ] Treat PCI id->driver_data (intel_vsec_platform_info) as read-only by making vsec_priv->info a const pointer and updating all function signatures to accept const intel_vsec_platform_info *. This improves const-correctness and clarifies that the platform info data from the driver_data table is not meant to be modified at runtime. No functional changes intended. Signed-off-by: David E.
