cache-l2x0.c: silence compiler warning
Fix commit '46a30aca7f5c MLK-20052 L2 Cache TEE/Linux shared mutex' when CONFIG_OPTEE is not defined. Compiler warning: | arch/arm/mm/cache-l2x0.c:151:12: warning: ‘l2c_set_mutex’ defined but not used [-Wunused-function] fns.set_mutex and l2c_set_mutex() are guarded by CONFIG_OPTEE. On top of that the function pointer is tested for NULL before calling. Signed-off-by: Max Krummenacher <>
