of_match_device() uses of_match_ptr() to make the match table argument NULL via the pre-processor when CONFIG_OF=n. This makes life harder for compilers who think that match tables are never used and warn about unused variables when CONFIG_OF=n. This series changes various callers to use of_device_get_match_data() instead, which doesn't have this problem, and removes the of_match_ptr() usage from of_match_device() so that the compiler can stop complaining about unused variables. It will do dead code elimination instead and remove the match table if it isn't actually used.
