From: Ilpo Järvinen <ilpo.jarvinen@xxxxxxxxxxxxxxx> [ Upstream commit c90b3b588e369c20087699316259fa5ebbb16f2d ] resctrl_val() function is called only by MBM, MBA, and CMT tests which means the else branch is never used. Both test branches call param->setup(). Remove the unused else branch and place the ->setup() call outside of the test specific branches reducing code duplication.
