When a module is driving multiple devices: does the
driver code itself have multiple instances, or is
there a single instance of the code which is
re-entrant??
thanks in advance...

Re-entrant.
Moreover the interrupt can can be shared, and based on the device file
opened, handling of other functions may differ in the driver.
