Subject: [PATCH] selftests/resctrl: Move ->setup() call outside of test
specific branches
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
References: bsc#1012628
Patch-mainline: 6.3.2
Git-commit: c90b3b588e369c20087699316259fa5ebbb16f2d
[ 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.
