The reason is that developers need to maintain the allocation and release of clk resources themselves, but this will increase the burden on developers. Using the API related to devm_clk_get_*_enable ensures that the life cycle of clk is consistent with that of the device, reducing the risk of unreleased resources like clk. Several other developers are also working on converting to more secure interfaces, and this patch set is in principle the same as theirs.
