From ea90383837334bcebe842e719ad4d8c966f4ef51 Mon Sep 17 00:00:00 2001 From: Baoyou Xie Date: Thu, 8 Sep 2016 19:03:20 +0800 Subject: [PATCH] drm/vc4: mark vc4_bo_cache_purge() static We get 1 warning when building kernel with W=1: drivers/gpu/drm/vc4/vc4_bo.c:147:6: warning: no previous prototype for 'vc4_bo_cache_purge' [-Wmissing-prototypes] In fact, this function is only used in the file in which it is declared and don't need a declaration, but can be made static. So this patch marks it 'static'.
