Message-ID: <20260217200004.698903271@linuxfoundation.org> (raw)
In-Reply-To: <20260217200004.221651386@linuxfoundation.org>

6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Brahmajit Das <listout@listout.xyz>

[ 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;
      |                   ^
