[Trixie][202511] EOPNOTSUPP Error Logged during AMD SFH HID Client Init

[ccroy-arista]

After upgrading SONiC to use Trixie, the kernel logs the following error message on boot: ... amd_sfh_hid_client_init failed err -95

The problem lies within the AMD Sensor Fusion Hub HID driver code in the kernel, and is a result of this change: torvalds/linux@2105e8e

The reason the above changes causes this issue is because it removes the guard against logging err -95 (-EOPNOTSUPP):

-		if (rc != -EOPNOTSUPP)
-			dev_err(&pdev->dev, "amd_sfh_hid_client_init failed\n");
 		return rc;

...

+	if (rc) {
+		amd_sfh_clear_intr(mp2);
+		dev_err(&pdev->dev, "amd_sfh_hid_client_init failed err %d\n", rc);
+		return;
+	}

This has been noticed on some Arista-7060X6 platforms, but likely affects other platforms/vendors as well.
