Nikhil Devshatwar 8c324ef0b4 media: ti-vpe: cal: Restrict DMA to avoid memory corruption ... [ Upstream commit 6e72eab2e7 ] When setting DMA for video capture from CSI channel, if the DMA size is not given, it ends up writing as much data as sent by the camera. This may lead to overwriting the buffers causing memory corruption. Observed green lines on the default framebuffer. Restrict the DMA to maximum height as specified in the S_FMT ioctl.
