Staging: Android: logger: module_exit implementation
This patch creates the module_exit for the android logger
so that it can be loaded and unloaded as a module.
The android logger is already declared as a tristate in the
Kconfig but the module_exit function was missing.
device_initcall works also with modprobe since include/linux/init.h:
#define module_init(x) __initcall(x);
...
#define __initcall(fn) device_initcall(fn)
Tested against f4a75d2eb7b1e2206094b901be09adb31ba63681 Linux 3.7-rc6
