Subject[PATCH 00/10] Stop NULLifying match pointer in of_match_device()
Date
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.
