This patch updates the documentation for the dwc3_request struct to
describe the purpose of the sg field. This field is a pointer to a
scatter-gather list used for managing memory buffers in DMA
operations during USB transfers.
- Add description for 'sg' in the doc block for dwc3_request
This change resolves a documentation warning related to the missing
description for this field.
