Subject: ERROR: drivers: net: ethernet: stmicro: stmmac: stmmac_main.c

Hi,

I automatically test (RC) kernel and caught ERROR word.
Please ignore, if its unimportant.

Kernel: 5.18-rc6
Arch: x86_64 (SMP)
Compiler: 7.5.0 (gcc)
FIle: drivers/net/ethernet/stmicro/stmmac/stmmac_main.c

Codebase Block:

static int stmmac_request_irq_multi_msi(struct net_device *dev)
{
        struct stmmac_priv *priv = netdev_priv(dev);
        enum request_irq_err irq_err;
        cpumask_t cpu_mask;
        int irq_idx = 0;
        char *int_name;
        int ret;
        int i;

        int_name = priv->int_name_mac;
        sprintf(int_name, "%s:%s", dev->name, "mac");
        ret = request_irq(dev->irq, stmmac_mac_interrupt,
                          0, int_name, dev);

        if (unlikely(ret < 0)) {
                netdev_err(priv->dev,
                           "%s: alloc mac MSI %d (error: %d)\n",
