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.
