From 897b6f4b4324b7696602fe386b5ea93506415442 Mon Sep 17 00:00:00 2001 From: Julien Grall Date: Mon, 30 Mar 2020 20:21:53 +0100 Subject: [PATCH] tools/libxc: misc: Mark const the parameter 'params' of xc_set_parameters() The parameter 'params' of xc_set_parameters() should never be modified. So mark it as const.
