From ec5c328606baacb98b6c8117de1396191cdbeeec Mon Sep 17 00:00:00 2001 From: Dmitry Nikiforov Date: Wed, 16 Apr 2025 23:51:19 +0300 Subject: [PATCH] media: davinci: vpif: Fix memory leak in probe error path commit 024bf40edf1155e7a587f0ec46294049777d9b02 upstream. If an error occurs during the initialization of `pdev_display`, the allocated platform device `pdev_capture` is not released properly, leading to a memory leak. Adjust error path handling to fix the leak. Found by Linux Verification Center (linuxtesting.org) with SVACE.
