This is a note to let you know that I've just added the patch titled media: venus: core: Fix a resource leak in the error handling path of 'venus_probe()' to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: media-venus-core-fix-a-resource-leak-in-the-error-ha.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 144a5ea39bfef14db22e3bce9145f228266f7392 Author: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> Date: Thu Aug 19 22:05:28 2021 +0200 media: venus: core: Fix a resource leak in the error handling path of 'venus_probe()' [ Upstream commit 8cc7a1b2aca067397a016cdb971a5e6ad9b640c7 ] A successful 'of_platform_populate()' call should be balanced by a corresponding 'of_platform_depopulate()' call in the error handling path of the probe, as already done in the remove function. A successful 'venus_firmware_init()' call should be balanced by a corresponding 'venus_firmware_deinit()' call in the error handling path of the probe, as already done in the remove function. Update the error handling path accordingly.
