If anyone has any objections, please let me know. ------------------ From: Brahmajit Das [ Upstream commit 1beee8d0c263b3e239c8d6616e4f8bb700bed658 ] The variable j is set, however never used in or outside the loop, thus resulting in dead code. Building with GCC 16 results in a build error due to -Werror=unused-but-set-variable= enabled by default. This patch clean up the dead code and fixes the build error. Example build log: drivers/gpu/drm/tegra/sor.c:1867:19: error: variable ‘j’ set but not used [-Werror=unused-but-set-variable=] 1867 | size_t i, j; | ^ Signed-off-by: Brahmajit Das Signed-off-by: Thierry Reding Link: https://lore.kernel.org/r/20250901212020.3757519-1-listout@listout.xyz Signed-off-by: Sasha Levin --- drivers/gpu/drm/tegra/hdmi.c | 4 ++-- drivers/gpu/drm/tegra/sor.c | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/tegra/hdmi.c b/drivers/gpu/drm/tegra/hdmi.c index 8cd2969e7d4bf..c4820f5e76581 100644 --- a/drivers/gpu/drm/tegra/hdmi.c +++ b/drivers/gpu/drm/tegra/hdmi.c @@ -658,7 +658,7 @@ static void tegra_hdmi_write_infopack(struct tegra_hdmi *hdmi, const void *data, { const u8 *ptr = data; unsigned long offset; - size_t i, j; + size_t i; u32 value; switch (ptr[0]) { @@ -691,7 +691,7 @@ static void tegra_hdmi_write_infopack(struct tegra_hdmi *hdmi, const void *data, * - subpack_low: bytes 0 - 3 * - subpack_high: bytes 4 - 6 (with byte 7 padded to 0x00) */ - for (i = 3, j = 0; i < size; i += 7, j += 8) { + for (i = 3; i < size; i += 7) { size_t rem = size - i, num = min_t(size_t, rem, 4); value = tegra_hdmi_subpack(&ptr[i], num); diff --git a/drivers/gpu/drm/tegra/sor.c b/drivers/gpu/drm/tegra/sor.c index 21f3dfdcc5c95..bc7dd562cf6b6 100644 --- a/drivers/gpu/drm/tegra/sor.c +++ b/drivers/gpu/drm/tegra/sor.c @@ -1864,7 +1864,7 @@ static void tegra_sor_hdmi_write_infopack(struct tegra_sor *sor, { const u8 *ptr = data; unsigned long offset; - size_t i, j; + size_t i; u32 value; switch (ptr[0]) { @@ -1897,7 +1897,7 @@ static void tegra_sor_hdmi_write_infopack(struct tegra_sor *sor, * - subpack_low: bytes 0 - 3 * - subpack_high: bytes 4 - 6 (with byte 7 padded to 0x00) */ - for (i = 3, j = 0; i < size; i += 7, j += 8) { + for (i = 3; i < size; i += 7) { size_t rem = size - i, num = min_t(size_t, rem, 4); value = tegra_sor_hdmi_subpack(&ptr[i], num); -- 2.51.0
