Subject: [PATCH 2/7] drivers/scsi/arm/{cumana_2,eesox,powertec}.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, the problem is only in the probe function.  The corresponding
call in the remove function already has the correct second argument.

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