[ 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.
