[ Upstream commit 7907cad7d07e0055789ec0c534452f19dfe1fc80 ]
MODULE_DEVICE_TABLE is used to extract the device information out of the driver and builds a table when being compiled. If using this macro, kernel can find the driver if available when the device is plugged in, and then loads that driver and initializes the device.
