The second parameter of IIO_DEVICE_ATTR_NAMED is a name which is
eventually stringified, not an arithmetic expression.
#define IIO_DEVICE_ATTR_NAMED(_vname, _name, _mode, _show, _store, \
_addr) \
struct iio_dev_attr iio_dev_attr_##_vname \
= IIO_ATTR(_name, _mode, _show, _store, _addr)
which is defined as:
#define IIO_ATTR(_name, _mode, _show, _store, _addr) \
{ .dev_attr = __ATTR(_name, _mode, _show, _store), \
.address = _addr }
which is defined as:
#define __ATTR(_name, _mode, _show, _store) { \
.attr = {.name = __stringify(_name), \
.mode = VERIFY_OCTAL_PERMISSIONS(_mode) }, \
.show = _show, \
.store = _store, \
}
