4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zenghui Yu <yuzenghui@xxxxxxxxxx>
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.
Fixes: 32bd44dc19de ("irqchip/gic-v3-its: Fix the incorrect parsing of VCPU table size")
