Re: [PATCH v4 0/3] DCMI bridge support

[Hugues FRUCHET]

Hi Hans,

You're welcome, here it is:

1) v4l-utils master branch, commit 
6aa15f7447d4aeca6af1ed7ee9644a0c7e891ece "v4l2-ctl: fix double 
decrementing of stream_count"

2) Cropping test is failed as usual because of OV5640 discrete framesizes

3) No more /dev/media* and /dev/v4l-*:
