[ Upstream commit f1c2765c6afcd1f71f76ed8c9bf94acedab4cecb ]
eiointc_domain_alloc() uses struct eiointc, which is not defined, for a pointer. Older compilers treat that as a forward declaration and due to assignment of a void pointer there is no warning emitted. As the variable is then handed in as a void pointer argument to irq_domain_set_info() the code is functional.
Use struct eiointc_priv instead.
