Previously 'we' do nothing. The current implementation casts inconrrectly.

mvebu_icu_msi_data. However, host_data actually stores a structure of
type msi_domain_info.

This incorrect assumption caused issues such as the thermal sensors of
the CP110 platform malfunctioning. Specifically, the translation of the
SEI interrupt to IRQ_TYPE_EDGE_RISING failed, 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

This commit resolves the issue by first casting host_data to

This commit is equally wrong as 'This patch'. See Documentation/process/

msi_domain_info and then accessing the mvebu_icu_msi_data through
msi_domain_info->chip_data.

I fixed it up for you.
