Subject: [RFC] mfd: mt6358: Using a single IRQ array instead of two companion
 arrays?

Hello,

I have taken another look also at the implementation of the function “mt6358_irq_init”.
https://elixir.bootlin.com/linux/v6.18-rc6/source/drivers/mfd/mt6358-irq.c#L227-L293

I see that there are two arrays allocated so far.
How do you think about the possibility to use a single array with the needed data instead?

Regards,
Markus
