* | [media] soc_camera: Support VIDIOC_EXPBUF ioctlKazunori Kobayashi2014-09-26

* | [media] mx2-camera: potential negative underflow bugDan Carpenter2014-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My static checker complains: drivers/media/platform/soc_camera/mx2_camera.c:1070 mx2_emmaprp_resize() warn: no lower bound on 'num' The heuristic is that it's looking for values which the user can influence and we put an upper bound on them but we (perhaps accidentally) allow negative numbers. I am not very familiar with this code but I have looked at it and think there might be a bug. Making the variable unsigned seems like a safe option either way and this silences the static checker warning. The call tree is: -> subdev_do_ioctl() -> mx2_camera_set_fmt() -> mx2_emmaprp_resize() The check: if (num > RESIZE_NUM_MAX) can underflow and then we use "num" on the else path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible to call STREAMON without having any buffers queued. So vb2_is_streaming() can return true without start_streaming() having been called. Only after at least one buffer has been queued will start_streaming be called. The check vb2_is_streaming() is incorrect as this would start the DMA without having proper DMA pointers set up. this patch uses vb2_start_streaming_called() instead to check is streaming was called.
