drm/tegra: hdmi: sor: Fix error: variable ‘j’ set but not used
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;
