This is a note to let you know that I've just added the patch titled PNP: fix name memory leak in pnp_alloc_dev() to the 6.1-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: pnp-fix-name-memory-leak-in-pnp_alloc_dev.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit b93fed44825f20829529cc607ce729fe9c7bb4c3 Author: Yang Yingliang <yangyingliang@xxxxxxxxxx> Date: Fri Nov 11 09:23:58 2022 +0800 PNP: fix name memory leak in pnp_alloc_dev() [ Upstream commit 110d7b0325c55ff3620073ba4201845f59e22ebf ] After commit 1fa5ae857bb1 ("driver core: get rid of struct device's bus_id string array"), the name of device is allocated dynamically, move dev_set_name() after pnp_add_id() to avoid memory leak.
