clk: imx: imx8-acm: Convert to platform remove callback returning void

2024-03-08T23:18:36Z

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

clk: imx: imx8mp: Fix SAI_MCLK_SEL definition

2024-02-26T09:05:58Z

There is SAI1, SAI2, SAI3, SAI5, SAI6, SAI7 existing in this block control, the order is discontinuous. The definition of SAI_MCLK_SEL(n) is not match with the usage of CLK_SAIn(n). So define SAI##n##_MCLK_SEL separately to fix the issue.

2024-02-26T08:58:42Z

The function “kfree” was called in up to three cases by the function “__imx8m_clk_hw_composite” during error handling even if the passed variables contained a null pointer. Adjust jump targets according to the Linux coding style convention.

clk: imx: scu: Fix memory leak in __imx_clk_gpr_scu()

2023-12-20T09:32:18Z

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.
