-Subject: [PATCH] dwc_otg: constrain endpoint max packet and transfer
- size on split IN
-
-The hcd would unconditionally set the transfer length to the endpoint
-packet size for non-isoc IN transfers. If the remaining buffer length
-was less than the length of returned data, random memory would get
-scribbled over, with bad effects if it crossed a page boundary.
-
-Force a babble error if this happens by limiting the max transfer size
-to the available buffer space. DMA will stop writing to memory on a
-babble condition.
-
-The hardware expects xfersize to be an integer multiple of maxpacket
-size, so override hcchar.b.mps as well.
