From 57ea76fd1ca072b3024f55cb461628d982acf873 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 2 Jun 2023 19:28:46 +0100 Subject: ARM: 9306/1: cacheflush: avoid __flush_anon_page() missing-prototype warning The prototype for __flush_anon_page() is intentionally hidden inside the flush_anon_page() inline function to prevent it from being called from drivers. When building with 'W=1', this causes a warning: arch/arm/mm/flush.c:358:6: error: no previous prototype for '__flush_anon_page' [-Werror=missing-prototypes] Work around this by adding a prototype directly next to the function definition.
