Subject: [PATCH 3/7] drivers/net/irda/{ali-ircc,via-ircc,w83977af-ir}.c: ensure arguments to request_irq and free_irq are compatible

From: Julia Lawall <Julia.Lawall@...6.fr>

Convert calls to free_irq so that the second argument is the same as the
last argument of the corresponding call to request_irq.  Without this
property, free_irq does nothing.

In each case, there is one call to free_irq with self as the second
argument and one with dev as the second argument.  Even though dev was also
the last argument of request_irq, I have changed all of the calls to use
self, as it fits better with the first argument to each function.

Signed-off-by: Julia Lawall <Julia.Lawall@...6.fr>

Not tested.  I don't know if I have made the right choice.
