I don't think it will make a difference. I'll have to move
#ifdef around the caller of hidma_free_msis instead which
I think is uglier.

The hidma_write_msi_msg function gets called only when 
CONFIG_GENERIC_MSI_IRQ_DOMAIN is defined. If I don't put 
this around the function definition, I get unused function
warning from the compiler. This is the reason why preprocessor
definition is outside of the function definition.
