Subject: [PATCH AUTOSEL 6.1 43/58] pinctrl: at91: use devm_kasprintf() to avoid potential leaks
Date: Sun, 26 Feb 2023 21:04:41 -0500	[thread overview]
Message-ID: <20230227020457.1048737-43-sashal@kernel.org> (raw)
In-Reply-To: <20230227020457.1048737-1-sashal@kernel.org>

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.
