Add format and argument checking and fix misuses in the dbg macro. Add __printf Use %pR for resource Add #include guard to samsung.h Move static functions from .h to .c Use vscnprintf instead of length unguarded vsprintf Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
