Hello Even Xu,

Commit 5282e45ccbfa ("HID: intel-thc-hid: intel-quicki2c: Add THC
QuickI2C ACPI interfaces") from Jan 6, 2025 (linux-next), leads to
the following Smatch static checker warning:

	drivers/hid/intel-thc-hid/intel-quicki2c/pci-quicki2c.c:59 quicki2c_acpi_get_dsm_property()
	warn: potential memory corrupting cast 4 vs 2 bytes

   119          struct quicki2c_subip_acpi_parameter i2c_param;

   122  
   123          if (!adev) {
   124                  dev_err(qcdev->dev, "Invalid acpi device pointer\n");
   125                  return ret;
   126          }
   127  
   128          qcdev->acpi_dev = adev;
   129  
   130          ret = quicki2c_acpi_get_dsm_property(adev, &i2c_hid_guid,

                                                     ^^^^^^^^^^^^^^^^^
This says INTEGER

   134                                               &qcdev->hid_desc_addr);
                                                     ^^^^^^^^^^^^^^^^^^^^^
But this is a u16 so it corrupts memory.

   135          if (ret)
   136                  return ret;
   137
