Hi Maarten, sorry about that, I will fix this for V6. Somehow my automated compile script tested each patch separately, including this one, but the defconfig didn't enable the module sc6is7xx, so the error went unnoticed. I wrongly assumed that "make alldefconfig" enabled all modules, I will instead use "make allyesconfig". Hugo.
