We get 2 warnings when building kernel with W=1: drivers/gpu/drm/bridge/analogix/analogix_dp_core.c:1053:5: warning: no previous prototype for 'analogix_dp_get_modes' [-Wmissing-prototypes] drivers/gpu/drm/bridge/analogix/analogix_dp_core.c:1097:1: warning: no previous prototype for 'analogix_dp_detect' [-Wmissing-prototypes] In fact, both functions are only used in the file in which they are declared and don't need a declaration, but can be made static. So this patch marks both functions with 'static'.
