This series addresses the following problems: - Fix receive buffer corruptions - Fix receive transfers with 0 byte transfer length - Abort transactions after unknown receive errors if the receive buffer is full - Reduce "trimming xfer length" logging noise The problems fixed with this series were observed when connecting a DM9600 Ethernet adapter to Veyron Chromebooks such as the ASUS Chromebook C201PA. The series was tested extensively with this and other adapters. The observed problems are also reported when tethering various phones, so test coverage with such phones would be very appreciated. ---------------------------------------------------------------- Guenter Roeck (4): usb: dwc2: Simplify and fix DMA alignment code usb: dwc2: Do not update data length if it is 0 on inbound transfers usb: dwc2: Abort transaction after errors with unknown reason usb: dwc2: Make "trimming xfer length" a debug message drivers/usb/dwc2/hcd.c | 82 ++++++++++++++++++++++++--------------------- drivers/usb/dwc2/hcd_intr.c | 14 +++++++- 2 files changed, 56 insertions(+), 40 deletions(-)
