I think 'count' is also required to be a power of 2.
so you could have checked 'addr & (size - 1)'.

It is required to be, and that is checked elsewhere
(in gsi_channel_data_valid()).  And yes, size would
therefore be a power-of-2, and so your clever test
would be a simple test.

I'll take that into account when I implement the
fix.  Thanks for the suggestion.
