#1662135 — [PATCH 01/11] HID: hid-core: convert to use DRIVER_ATTR_RO and drv_groups

In the quest to get rid of DRIVER_ATTR(), this patch converts the
hid-core code to use DRIVER_ATTR_RO() and also moves to use drv_groups
as creating individual sysfs files is not good (it races with userspace
notifications.)

#1662136 — [PATCH 02/11] IB: nes: convert to use DRIVER_ATTR_RW

We are trying to get rid of DRIVER_ATTR(), and all of the nes.c driver
attributes can be trivially changed to use DRIVER_ATTR_RW(), making the
code smaller and easier to manage over time.
