that you don't need to go through this look 16 times even if a single bit is set: Nice example here: https://elixir.bootlin.com/linux/latest/source/drivers/irqchip/irq-ts4800.c#L81 status = irq_status; do { j = __ffs(status); status &= ~BIT(j); } while(status); > + hwirq = mt6358_ints[top_gp].hwirq_base + > + MT6358_REG_WIDTH * i + j; > + > + virq = irq_find_mapping(chip->irq_domain,

this: for (i = 0; i < mt6358_irq_data->num_top; i++) { bit = BIT(mt6358_ints[i].top_offset); if (top_irq_status & bit) { mt6358_irq_sp_handler(chip, i); top_irq_status &= ~bit; if (!top_irq_status)
