Subject: pinctrl: at91: use devm_kasprintf() to avoid potential leaks

From: Claudiu Beznea <claudiu.beznea@microchip.com>

[ 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.
