4.19-stable review patch. If anyone has any objections, please let me know.

commit 8d565748b6035eeda18895c213396a4c9fac6a4c upstream.
In current logic, its_parse_indirect_baser() will be invoked twice when allocating Device tables. Add a *break* to omit the unnecessary and annoying (might be ...) invoking.
