Subject: [PATCH v2 05/26] selftests/resctrl: Mark get_cache_size() cache_type const
Date:   Mon, 20 Nov 2023 13:13:19 +0200
Message-Id: <20231120111340.7805-6-ilpo.jarvinen@linux.intel.com>

get_cache_size() does not modify cache_type so it could be const.

Mark cache_type const so that const char * can be passed to it. This
prevents warnings once many of the test parameters are marked const.
