This is a note to let you know that I've just added the patch titled clk: imx: avoid memory leak 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: clk-imx-avoid-memory-leak.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 7cd232dd00d3e764e0b476484ca1e08871737888 Author: Peng Fan <peng.fan@xxxxxxx> Date: Wed Jan 4 19:00:29 2023 +0800 clk: imx: avoid memory leak [ Upstream commit f4419db4086e8c31821da14140e81498516a3c75 ] In case imx_register_uart_clocks return early, the imx_uart_clocks memory will be no freed. So execute kfree always to avoid memory leak.
