If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 80d0997e784f692805900fe94d49bab55bb25e57 Author: Claudiu Beznea <claudiu.beznea@xxxxxxxxxxxxx> Date: Fri Feb 3 15:27:14 2023 +0200 pinctrl: at91: use devm_kasprintf() to avoid potential leaks [ Upstream commit 1c4e5c470a56f7f7c649c0c70e603abc1eab15c4 ] Use devm_kasprintf() instead of kasprintf() to avoid any potential leaks. At the moment drivers have no remove functionality thus there is no need for fixes tag.
