This is a note to let you know that I've just added the patch titled wifi: ipw2200: fix memory leak in ipw_wdev_init() to the 4.19-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: wifi-ipw2200-fix-memory-leak-in-ipw_wdev_init.patch and it can be found in the queue-4.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 50a6cdae99f0a62acf45dab8051dc6b211696ff8 Author: Zhengchao Shao <shaozhengchao@xxxxxxxxxx> Date: Fri Dec 9 09:24:22 2022 +0800 wifi: ipw2200: fix memory leak in ipw_wdev_init() [ Upstream commit 9fe21dc626117fb44a8eb393713a86a620128ce3 ] In the error path of ipw_wdev_init(), exception value is returned, and the memory applied for in the function is not released. Also the memory is not released in ipw_pci_probe(). As a result, memory leakage occurs. So memory release needs to be added to the error path of ipw_wdev_init().
