[PATCH v2] staging: android: ion: use macro DEFINE_DEBUGFS_ATTRIBUTE to define debugfs fops
It is more clear to use DEFINE_DEBUGFS_ATTRIBUTE to define debugfs file operation rather than DEFINE_SIMPLE_ATTRIBUTE.
Found using coccinelle.

No, it is not "more clear", the two defines are not the same thing, they do different things. If they were just identical, we would not need them both :)
So please be very explicit as to _why_ you want to change this, and show how you have verified that changing this is the correct thing to do, and how you tested. Because the user-visible change can be quite different with this type of kernel change.
