This patch straddles the border of acceptable. The pointless obfuscation
is balanced against the removal of explicit type in list_entry() and thus
a possible mismatched struct. I'm not acking nor naking this.
A list_for_each() followed by list_entry() ---> list_for_each_entry()
conversion is a pretty harmless (and desirable) conversion, IMO.
In fact list_for_each_entry() itself uses list_entry(..., typeof(*p), ...)
which seems to be a safer way to use list_entry() than specifying
the type explicity/manually in its arguments, no?
