This is a note to let you know that I've just added the patch titled platform/x86: intel_scu_ipc: fix possible name leak in __intel_scu_ipc_register() 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: platform-x86-intel_scu_ipc-fix-possible-name-leak-in.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 51ad461485016e1162e19c9575c622188ca0e0b3 Author: Yang Yingliang <yangyingliang@xxxxxxxxxx> Date: Thu Dec 8 23:19:16 2022 +0800 platform/x86: intel_scu_ipc: fix possible name leak in __intel_scu_ipc_register() [ Upstream commit 0b3d0cb7c0bed2fd6454f77ed75e7a662c6efd12 ] In some error paths before device_register(), the names allocated by dev_set_name() are not freed. Move dev_set_name() front to device_register(), so the name can be freed while calling put_device().
