We get 1 warning when building kernel with W=1: drivers/gpu/drm/i2c/tda998x_drv.c:1292:5: warning: no previous prototype for 'tda998x_audio_digital_mute' [-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 this function with 'static'.
