[PATCH 0/7] irqchip/gic-v5: Misc fixes following sashiko's report

While reviewing this series [1] sashiko spotted some issues [2] in the GICv5
host driver.

This short series addresses them along with other minor issues spotted
in the resulting code review following sashiko's report.

Issues short description:

* Check get_logical_index() return value in MADT IAFFID parsing that might cause
  out-of-bounds per CPU array indexing
* Add a check for !NULL LPI domain on LPI domain teardown
* Disable enabled IRSes on GICv5 driver probe failure
* Fix gicv5_init_common() error paths handling (clean-up paths were
  missing some runtime error conditions and clean-up)
* Release IRS iomem regions on OF probe and driver failures
* Fix smp_processor_id() usage on two preemptible code paths:
  - LPI/SPI IAFFID initialization
  - Dynamic L2 IST table entry initialization

This series depends (as in, applies cleanly on top) on [3] as reported with
the message-id tag.
