Build error for controller with mellinger

[kyuhyong]

I fresh git cloned the fw, submodule update
I modified the Makefile to use mellinger
ESTIMATOR ?= kalman
CONTROLLER ?= mellinger # one of Any, PID, Mellinger

When tried to build by calling make PLATFORM=CF2 I got error below.

src/modules/src/controller.c: In function 'controllerInit':
<command-line>:0:17: error: 'ControllerTypemellinger' undeclared (first use in this function)
src/modules/src/controller.c:38:37: note: in expansion of macro 'CONTROLLER_NAME'
   ControllerType forcedController = CONTROLLER_NAME;
                                     ^
<command-line>:0:17: note: each undeclared identifier is reported only once for each function it appears in
src/modules/src/controller.c:38:37: note: in expansion of macro 'CONTROLLER_NAME'
   ControllerType forcedController = CONTROLLER_NAME;
                                     ^
tools/make/targets.mk:26: recipe for target 'controller.o' failed

I realized controller.c is newly added and looks like there is a bug in it.

Nevermind, changing mellinger to Mellinger actually correct the error.
My mistake.
