It's a bit unusual to need to actually free the IRQ over suspend - what's driving that requirement here?
clk_disable_unprepare(dspi->clk); is driving the requirement - same as in dspi_remove case, the module will fault when its registers are accessed without a clock.
In few cases when I have shared interrupt in different drivers, they were just disabling it during suspend. Why it has to be freed?
