Hi Pavel,

I tried to apply it here, but it seems that there are something
wrong with the patch:

$ quilt push -f --merge

Applied patch patches/lmml_50901_libv4l_make_libv4l2_usable_on_devices_with_complex_pipeline.patch (forced; needs refresh)

I even tried to reset the tree to a patchset earlier than July, 8.
Same issue.

I could manually try to fix it, but that misordered hunks
warning is weird. Makes me wonder if the patch is not mangled.

Could you please re-send it on the top of upstream? Better to use
git send-email, as it won't mangle your patch.

Alternatively, please send me a ssh public key in private, and I'll
give you access to the repository where you can store those patches.

Thanks!
Mauro

Thanks,
