Some variables are set but never used. To avoid warning when compiling with W=1 and keep the algorithm like it is tag theses variables with _maybe_unused macro. Signed-off-by: Benjamin Gaignard <benjamin.gaignard@st.com> --- changes in this version: - do not modify the code to remove the unused variables just prefix them with __maybe_unused macro. drivers/gpu/drm/drm_modes.c | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-)
