Subject: [PATCH 6/7] drivers/input/touchscreen/hp680_ts_input.c: ensure arguments to request_irq and free_irq are compatible

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

Change 0 to NULL in the last argument of request_irq, since the argument
should have pointer type and so that the last argument of request_irq
syntactically matches the second argument of the later call to free_irq.

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