Subject: [PATCH 2/2] 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.

 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
+macro that works identically to the DEVICE_ATTR_RW and DEVICE_ATTR_RO
+macros.
 
 Example:
 
-DRIVER_ATTR(debug,0644,show_debug,store_debug);
+DRIVER_ATTR_RW(debug);
 
 This is equivalent to declaring:
