[PATCH 0/6] isa: Ensure number of irq matches number of base

Several ISA drivers support IRQ and call devm_request_irq() in their
device probe callbacks. These drivers typically provide an "irq" array
module parameter, which matches with the respective "base" array module
parameter, to specify what IRQ lines are used for each device. To reduce
code repetition, a module_isa_driver_with_irq helper macro is introduced
providing a check ensuring that the number of "irq" passed to the module
matches with the respective number of "base". The relevant ISA drivers
are updated accordingly to utilize the new module_isa_driver_with_irq
macro.
