commit 987f379b54091cc1b1db986bde71cee1081350b3 upstream.
mvebu_icu_translate() incorrectly casts irq_domain::host_data directly to mvebu_icu_msi_data. However, host_data actually points to a structure of type msi_domain_info.
This incorrect cast causes issues such as the thermal sensors of the CP110 platform malfunctioning. Specifically, the translation of the SEI interrupt to IRQ_TYPE_EDGE_RISING fails, preventing proper interrupt handling. The following error was observed:
genirq: Setting trigger mode 4 for irq 85 failed (irq_chip_set_type_parent+0x0/0x34) armada_thermal f2400000.system-controller:thermal-sensor@70: Cannot request threaded IRQ 85
Resolve the issue by first casting host_data to msi_domain_info and then accessing mvebu_icu_msi_data through msi_domain_info::chip_data.
