Subject: [PATCH 4.4 20/40] mfd: axp20x: Fix axp288 PEK_DBR and PEK_DBF irqs being swapped

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans de Goede <hdegoede@...hat.com>


[ Upstream commit 1af468ebe45591651ec3bafc2e9ddc6fdef70ae0 ]

The R in PEK_DBR stands for rising, so it should be mapped to
AXP288_IRQ_POKP where the last P stands for positive edge.

Likewise PEK_DBF should be mapped to the falling edge, aka the
_N_egative edge, so it should be mapped to AXP288_IRQ_POKN.

This fixes the inverted powerbutton status reporting by the
axp20x-pek driver.
