driver core: remove DRIVER_ATTR
DRIVER_ATTR is no longer in use, and driver authors should be using DRIVER_ATTR_RW() or DRIVER_ATTR_RO() or DRIVER_ATTR_WO() instead in order to always get the permissions correct. So remove it so that no one can use it anymore. Acked-by: Alan Tull <atull@kernel.org> Reviewed-by: Moritz Fischer <mdf@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Device drivers can export attributes via their sysfs directories.
-Drivers can declare attributes using a DRIVER_ATTR macro that works
-identically to the DEVICE_ATTR macro.
+Drivers can declare attributes using a DRIVER_ATTR_RW and DRIVER_ATTR_RO

Example:
-DRIVER_ATTR(debug,0644,show_debug,store_debug);

This is equivalent to declaring:
