Hi,

I tried to debug streaming in libcamera, where I stumbled upon this. I asked around on IRC where I was told that this statement in the documentation is wrong, so I'm submitting a removal.

Cheers,
Dorota Czaplejewicz

For future reference: a patch needs to start with a commit message,
followed by your Signed-off-by, then '---' and the patch itself.

I've taking the paragraph above as the commit message, so no need for
you to do anything here.

Regards,

	Hans
