STRUCT MLXSW_I2C(9)

🎀 NAME 🎀

struct mlxsw_i2c — device private data:

okay so this page is from the Kernel API Manual, and this struct is literally the device's private-data situation. no cap, it's giving “everything the driver needs in one cozy little bag” 💅✨

✨ SYNOPSIS ✨

the whole struct, exactly as it shows up, bestie:

       struct mlxsw_i2c {
           struct {
             u32 mb_size_in;
             u32 mb_off_in;
             u32 mb_size_out;
             u32 mb_off_out;
             struct mutex lock;
           } cmd;
           struct device *dev;
           struct mlxsw_core *core;
           struct mlxsw_bus_info bus_info;
           u16 block_size;
           struct mlxreg_core_hotplug_platform_data *pdata;
           struct work_struct irq_work;
           int irq;
        };
