+From: Thierry Reding <treding@nvidia.com>
+
+regmap_add_irq_chip() will try to allocate all of the IRQ descriptors
+upfront if passed a non-zero irq_base parameter. However, the intention
+is to allocate IRQ descriptors on an as-needed basis if possible. Pass 0
+instead of -1 to fix that use-case.
