[PATCH] mfd: max8907: Remove IRQF_NO_AUTOEN flag
From: Sergey Larin
Date: Mon Jun 14 2021 - 18:33:19 EST
IRQF_NO_AUTOEN flag doesn't go well with IRQF_SHARED flag - the
check in request_threaded_irq fails and exits with EINVAL.
So we ignore the flag and enable it on the first IRQ request. No
interrupt should arrive from the chip as all interrupts are masked
by default.
