+	  specified clamp value. Both minimum and maximum task clamping cannot
+          be bigger than the corresponding clamping defined at task group level.
The 4 lines above should all be indented the same (one tab + 2 spaces).
Right... then there's definitively something broken with my vim
reformat shortcut, which sometimes uses spaces instead of tabs :(

Unfortunately this pattern is not covered by checkpatch, which
returns not errors/warnings on this patch.

Anyway, thanks for spotting it... easy fix for the next respin.

Best,
