Around DWC USB3 2.30a release another bit has been added to the Device-Specific Event (DEVT) Event Information (EvtInfo) bitfield. Because of that, what used to be 8 bits long, has become 9 bits long. Per dwc3 2.30a+ spec in the Device-Specific Event (DEVT), the field of Event Information Bits(EvtInfo) uses [24:16] bits, and it has 9 bits not 8 bits. And the following reserved field uses [31:25] bits not [31:24] bits, and it has 7 bits. So in dwc3_event_devt, the bit mask should be: event_info [24:16] 9 bits reserved31_25 [31:25] 7 bits This patch makes sure that newer core releases will work fine with Linux and that we will decode the event information properly on new core releases.
