I had not checked on this git. Thank you for pointing it out. I am
downloading the code from github, will rebase on top of it and check the
patches and push the next version correspondingly.

I could not sufficient details on
V4L2_CID_MPEG_VIDEO_HEVC_HIERARCHICAL_CODING_LAYER_CH in the User Manual
to implement this CID. Hence I wanted to remove it in v3 itself, I will
take care of this in next version.
