Subject: Re: [BUG] [PATCH v5 02/10] mfd: mt6397: extract irq related code from core driver

As far as i understand does old init-function not rely on the chip-id, so it seems that with this commit a prior bug is shown.
maybe the chip-id (should be 0x23 like constant) is set later after irq-request or completely missing for mt6323
