From f38ba5459ced3441852f37f20fcfb7bd39d20f62 Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Thu, 25 Jul 2024 09:46:32 -0700 Subject: [PATCH] spmi: pmic-arb: Pass the correct of_node to irq_domain_add_tree Currently, irqchips for all of the subnodes (which represent a given bus master) point to the parent wrapper node. This is no bueno, as no interrupts arrive, ever (because nothing references that node). Fix that by passing a reference to the respective master's of_node. Worth noting, this is a NOP for devices with only a single master described.
