Subject: [PATCH 04/24] selftests/resctrl: Mark get_cache_size() cache_type const
Date:   Tue, 24 Oct 2023 12:26:14 +0300
Message-Id: <20231024092634.7122-5-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.
