[Linux-stable-mirror] [PATCH 1/3] Input: synaptics_rmi4 - do not delete interrupt memory too early
We want to free memory reserved for interrupt mask handling only after we free functions, as function drivers might want to mask interrupts. This is needed for the followup patch to the F03 that would implement unmasking and masking interrupts from the serio pass-through port open() and close() methods.
