Why?
Can't it be done in the ->init_hw() callback of GPIO IRQ chip?

Hi Andy:
The initialization state of EIC is high-level trigger. If the external
level is high and the interrupt condition is met,
EIC has a latch function. If the module registers the eic interrupt,
an interrupt will be generated immediately
as soon as the eic interrupt is enabled. To solve this problem, our
processing method is to clear the interrupt
once when setting the interrupt trigger type, in order to avoid that
this interrupt is the last interrupt.
Thanks

Obvious question, isn't this needed to be added to ->init_hw() as well?

In the ->init_hw() function, the sprd_gpio_irq_ack interface will be called
to clear the interrupt, and there is no need to add it repeatedly

Sorry, NAK. The commit message is meaningless.
