In enum trace_buffer_source, GX_DBGC and CX_DBGC are missing the leading @ prefix (@GX_DBGC: and @CX_DBGC:), causing kernel-doc to warn that both enum values are undescribed. In struct adreno_snapshot_trace_buffer, the top-level comment header omits the struct keyword ("adreno_snapshot_trace_buffer:" instead of "struct adreno_snapshot_trace_buffer -"), which causes kernel-doc to treat it as a function prototype and fail. Additionally, the inline comment for the segment member is a copy-paste duplicate of @dbgc_ctrl rather than @segment. Finally, struct adreno_snapshot_eventlog and struct adreno_snapshot_gmu_version use inline /** @member: ... */ kernel-doc comments on their fields without a preceding /** struct ... */ kernel-doc header on the enclosing structures. Could these comments be updated to follow standard kernel-doc syntax (or converted to regular /* ... */ comments if kernel-doc generation is not intended)?
