6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ladislav Michl <ladis@xxxxxxxxxxxxxx> [ Upstream commit 3609699c32aa4f2710a6fe2b21afc6a9a3c66bc5 ] Rename dwc3_data to dwc3_am62 to make it consistent with other glue drivers, it's clearer that this is am62's specific. While there, do the same for data variable.
