6.7-stable review patch. If anyone has any objections, please let me know. ------------------ From: Kuan-Wei Chiu <visitorckw@xxxxxxxxx> [ Upstream commit bfbea9e5667cfa9552c3d88f023386f017f6c308 ] In cases where kcalloc() fails for the 'clk_data->clks' allocation, 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_data' before returning.
