From: Nicolas Pitre <npitre@xxxxxxxxxxxx>
Some systems don't always populate sensor controller slots starting
at slot 0. Use a bitmap instead of a count to indicate valid sensor
slots. Also create a pretty iterator for that.
About that iterator: it causes checkpatch to complain with "ERROR:
Macros with multiple statements should be enclosed in a do - while
loop". However this is not possible here. And many similar iterators
do exist using the same form in the tree already.
