PS1, Line 9: There is a ACPI error message about no handler or method for GPE73 while
           : plugging a USB3 flash driver to a type-C-to-A dongle. The PMC_GPE0_DW2
           : is routed to GPP_E and GPP_E9/USB_OC0# is mapped to GPE73. This change
           : adds a dummy GPE Method _L73 for USB overcurrent indication. Kernel
           : driver suspends the bus and host controller which avoids the host halted
           : in USB overcurrent state.
This is really strange... I wonder if there's a bug in the kernel. The comment above the line where the error msg is printed says:
```
                /*
                 * No handler or method to run!
                 * 03/2010: This case should no longer be possible. We will not allow
                 * a GPE to be enabled if it has no handler or method.
                 */

```

So for some reason the GPE is enabled even though there is no handler for it.
