arm/mach-integrator/time.c, mwave: revert portions of recent irq cleanups
The recent irq cleanups for arch/arm/mach-integrator/time.c and drivers/char/mwave/tp3780i.c changed the request_irq() dev_id parameter, but neglected to change the matching free_irq() parameter, thus creating a bug upon irq de-registration. Given that the impetus for the changes is not yet accepted upstream, it is best to revert the irq cleanups. Mostly. A comment is added to time.c to reduce future confusion, of type that led to my time.c cleanup in the first place. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
