From cad237b6c875fbee5d353a2b289e98d240d17ec8 Mon Sep 17 00:00:00 2001 From: Abdun Nihaal Date: Tue, 23 Dec 2025 11:19:01 +0530 Subject: [PATCH] media: i2c/tw9906: Fix potential memory leak in tw9906_probe() In one of the error paths in tw9906_probe(), the memory allocated in v4l2_ctrl_handler_init() and v4l2_ctrl_new_std() is not freed. Fix that by calling v4l2_ctrl_handler_free() on the handler in that error path.
