It is not being used in the typical way for > a mask. It is the mask of all the reset bits, see also patch 3/3. Either all these bits are set or none. Do you have any suggestion? I thought about adding mask and value for the remap_update_bits() in patch 3/3 but decided against it, just because it doesn't add any value because mask and value are the same. -michael
