Subject: [PATCH 4.14 107/183] irqchip/gic-v3-its: Avoid parsing _indirect_ twice for Device table

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


From: Zenghui Yu <>

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")
