From ed05c71a574235aec3418d2b5c94f24ae84cc2db Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 17 Aug 2023 16:26:44 +0200 Subject: [PATCH] powerpc/47x: Remove early_init_mmu_47x() to fix no previous prototype 4xx/iss476-smp_defconfig leads to: CC arch/powerpc/mm/nohash/tlb.o arch/powerpc/mm/nohash/tlb.c:322:13: error: no previous prototype for 'early_init_mmu_47x' [-Werror=missing-prototypes] 322 | void __init early_init_mmu_47x(void) | ^~~~~~~~~~~~~~~~~~ early_init_mmu_47x() is used only at one place and only locally. Fold it into its only caller and remove it.
