[PATCH AUTOSEL 5.15 31/35] clk: imx: scu: Fix memory leak in __imx_clk_gpr_scu()

[Sasha Levin]

From: Kuan-Wei Chiu <visitorckw@xxxxxxxxx>

[ 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.
