✨ SYNOPSIS ✨

here's the whole struct, bestie — keep it exactly like this, no cap:

struct mip_priv {
    spinlock_t lock;
    void __iomem            *base;
    u64 msg_addr;
    u32 msi_base;
    u32 num_msis;
    u32 msi_offset;
    unsigned long           *bitmap;
    struct irq_domain       *parent;
    struct device           *dev;
};
