Subject: [PATCH AUTOSEL 5.15 31/35] clk: imx: scu: Fix memory leak in __imx_clk_gpr_scu()
Date: Mon, 22 Jan 2024 10:12:28 -0500 [thread overview]
Message-ID: <20240122151302.995456-31-sashal@kernel.org> (raw)
In-Reply-To: <20240122151302.995456-1-sashal@kernel.org>
From: Kuan-Wei Chiu <visitorckw@gmail.com>
[ Upstream commit 21c0efbcb45cf94724d17b040ebc03fcd4a81f22 ]
In cases where imx_clk_is_resource_owned() returns false, the code path
does not handle the failure gracefully, potentially leading to a memory
leak. This fix ensures proper cleanup by freeing the allocated memory
for 'clk_node' before returning.
