From: Hans Verkuil <hans.verkuil at cisco.com>

Instead of doing:

	if (state->cec_enabled_adap)
		adv7511_wr_and_or(sd, 0x95, 0xc0, enable ? 0x39 : 0x00);

do:

	adv7511_wr_and_or(sd, 0x95, 0xc0,
			  (state->cec_enabled_adap && enable) ? 0x39 : 0x00);

This ensures that the cec irq mask is always updated correctly according
to both conditions.
