Moving away from regulator bulk get to regulator bulk get?

Why are you unwinding regulator_bulk_get() with an open coded
regulator_bulk_put()?

Also please think hard before including complete backtraces in upstream
reports, they are very large and contain almost no useful information
relative to their size so often obscure the relevant content in your
message. If part of the backtrace is usefully illustrative then it's
usually better to pull out the relevant sections.
