Subject: arm64: constify icache_policy_str[]
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0bf136a8cf11502643c27c8de1b1db8f161a31ed;p=openwrt%2Fstaging%2Fblogic.git

arm64: constify icache_policy_str[]

The icache_policy_str[] array contains compile-time constant data, and
is never intentionally modified, so let's mark it as const.
