A comment explaining why would have been nice.

I don't quite get why you need mindepth / maxdepth here, we just want to
move all files to usr/lib.

usr/lib/imx-mm contains the following subdirs:

tree -d target/usr/lib/imx-mm
target/usr/lib/imx-mm
├── audio-codec
│   └── wrap
└── video-codec

So I dropped those flags and committed, thanks.
