greybus: audio: bound the topology section sizes against the fetched size<\/p>\n
gb_audio_gb_get_topology() fetches a topology blob of a module-supplied

\nmodule-supplied size_dais, size_controls and size_widgets fields to

\nare never checked against the fetched blob, so a module reporting a
\nsmall topology size but large section sizes makes the offsets point
\npast the allocation, and parsing reads out of bounds.<\/p>\n
