Jeez, the code in this header is awful.
Let's improve this a bit more:
The 'size' argument in property_read is unused AFAICT, so remove it from that
macro and wherever it is used.
The 'signal, size' arguments of property_write is just a type, so replace
'signal, size' by prop_type. Update DEFINE_SYSFS_PROPERTY accordingly and
then all the DEFINE_SYSFS_PROPERTY lines become:
DEFINE_SYSFS_PROPERTY(power_state, unsigned int, "%u", 0)
which finally makes sense when you read it.
