Arnd Bergmann 332576e69a arm64: avoid -Woverride-init warning ... The icache_policy_str[] definition causes a warning when extra warning flags are enabled: arch/arm64/kernel/cpuinfo.c:38:26: warning: initialized field overwritten [-Woverride-init] 38 | [ICACHE_POLICY_VIPT] = "VIPT", | ^~~~~~ arch/arm64/kernel/cpuinfo.c:38:26: note: (near initialization for 'icache_policy_str[2]') arch/arm64/kernel/cpuinfo.c:39:26: warning: initialized field overwritten [-Woverride-init] 39 | [ICACHE_POLICY_PIPT] = "PIPT", | ^~~~~~ arch/arm64/kernel/cpuinfo.c:39:26: note: (near initialization for 'icache_policy_str[3]') arch/arm64/kernel/cpuinfo.c:40:27: warning: initialized field overwritten [-Woverride-init] 40 | [ICACHE_POLICY_VPIPT] = "VPIPT", | ^~~~~~~ arch/arm64/kernel/cpuinfo.c:40:27: note: (near initialization for 'icache_policy_str[0]') There is no real need for the default initializer here, as printing a NULL string is harmless. Rewrite the logic to have an explicit reserved value for the only one that uses the default value. This partially reverts the commit that removed ICACHE_POLICY_AIVIVT.
