Patch Review

**Status: Good to merge.**

This patch fixes 12 kernel-doc warnings where the comment prototype name didn't match the actual type name. Each fix is a one-line change to the `/** ... */` comment header. All corrections align the documented name with the actual declaration immediately following:

- `dmub_trace_code_t` → `typedef dmub_trace_code_t` (typedef needs the keyword)
- `struct dmub_shared_state_ips_fw` → `struct dmub_shared_state_ips_fw_signals`
- `struct dmub_shared_state_ips_signals` → `struct dmub_shared_state_ips_driver_signals`
- `struct dmub_shared_state_cursor_offload_v1` → `struct dmub_shared_state_cursor_offload_stream_v1`
- `enum dmub_shared_state_feature_common` → `struct dmub_shared_state_feature_common`
- `enum dmub_shared_state_feature_header` → `struct dmub_shared_state_feature_header`
- `struct dmub_cmd_read_modify_write_sequence` → `struct dmub_rb_cmd_read_modify_write`
- `struct dmub_rb_cmd_cab` → `struct dmub_rb_cmd_cab_for_ss`
- `struct dmub_cmd_set_pixel_clock_data` → `struct dmub_rb_cmd_set_pixel_clock`
- `union dpia_notify_data_type` → `union dpia_notification_data`
- `struct dmub_rb_cmd_hpd_sense_notify` → `struct dmub_rb_cmd_hpd_sense_notify_data`
- `struct dmub_cmd_cable_id_input` → `struct dmub_cmd_cable_id_output`

Each one is verified by checking that the corrected name matches the actual declaration that follows the comment block. No issues.
