PCI: sysfs: Change DEVICE_ATTR() to DEVICE_ATTR_WO()
DEVICE_ATTR() should only be used when files have unusual permissions.
Change DEVICE_ATTR() with '0220' write-only permissions to
DEVICE_ATTR_WO(), e.g.,
- static DEVICE_ATTR(_name, (S_IWUSR | S_IWGRP), NULL, _store);
+ static DEVICE_ATTR_WO(_name);
Since _store is no longer passed, make the _name passed by DEVICE_ATTR_WO()
and the related _name##_store() name match with each other, e.g.,
DEVICE_ATTR_WO(bus_rescan) must be able to call bus_rescan_store()
