If anyone has any objections, please let me know. ------------------ From: Mohammed EL Kadiri commit a51cea23e409278f6e2ea072280aba93cc1dd75e upstream. parse_caps() and parse_alloc_mode() return only the size of their fixed header fields, excluding the flexible array payload. hfi_parser() uses this return value to advance through the firmware response buffer, so underreporting causes parser desynchronization. Return the full consumed size (header + entries), matching the correct pattern used by parse_profile_level().
