From 6cbab9f0da72b4dc3c3f9161197aa3b9daa1fa3a Mon Sep 17 00:00:00 2001 From: Prateek Agarwal Date: Fri, 19 Sep 2025 13:25:40 +0900 Subject: [PATCH] drm/tegra: Add call to put_pid() Add a call to put_pid() corresponding to get_task_pid(). host1x_memory_context_alloc() does not take ownership of the PID so we need to free it here to avoid leaking.
