From 4531f128eac356144545b833908b6ffbc0292e16 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 17 Aug 2023 14:26:45 +0200 Subject: [PATCH] powerpc/8xx: Remove init_internal_rtc() to fix no previous prototype error A W=1 build of mpc885_ads_defconfig throws the following error: CC arch/powerpc/platforms/8xx/m8xx_setup.o arch/powerpc/platforms/8xx/m8xx_setup.c:41:1: error: no previous prototype for 'init_internal_rtc' [-Werror=missing-prototypes] 41 | init_internal_rtc(void) | ^~~~~~~~~~~~~~~~~ init_internal_rtc() was introduced by commit df34403dcaac ("[POWERPC] 8xx: Add mpc885ads support and common mpc8xx files") as a weak function but has never been defined and/or used outside m8xx_setup.c As it is called only once there, just fold it into its caller and remove it.
