I know that this is technically correct, but it's obfuscated IMHO.
'val' is set correctly only when of_property_read_u32(...) is "false",
which is doubly-weird because of_property_read_u32(...) doesn't
actually return a boolean.

I would rather you break this into two if-statements like the original code.
