If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit d07c26cb27f2e290924dd9f93c51cf9f807904ff Author: Jiasheng Jiang <jiasheng@xxxxxxxxxxx> Date: Fri Mar 4 10:38:21 2022 +0800 ASoC: wm8350: Handle error for wm8350_register_irq [ Upstream commit db0350da8084ad549bca16cc0486c11cc70a1f9b ] As the potential failure of the wm8350_register_irq(), it should be better to check it and return error if fails. Also, use 'free_' in order to avoid the same code.
