[PATCH 4.11 31/78] mfd: cpcap: Use ack_invert interrupts

From: Tony Lindgren <tony@atomide.com>

commit 5a88d4120029601a0868e20774382d312952d3b5 upstream.

We should use ack_invert as the int_read_and_clear() in the Motorola
kernel tree does "ireg_val & ~mreg_val" before writing to the mask
register.
