Are you sure this is correct?

/**
 * struct msm_gpio_wakeirq_map - Map of GPIOs and their wakeup pins
 * @gpio:          The GPIOs that are wakeup capable
 * @wakeirq:       The interrupt at the always-on interrupt controller
 */
struct msm_gpio_wakeirq_map {
	unsigned int gpio;
	unsigned int wakeirq;
};

MSM8998 has 150 GPIOs and 96 MPM IRQs. The tuple { 69, 145 } can't be
right because 145 is not a valid MPM pin. It's a valid GPIO though so
the original order was correct. Maybe replace "Fixes:" with "Breaks:"? :D
