Reading recent discussions [0] [1], I realized this change introduces a number of problems: - only converting to module_platform_driver creates the issue with the existing __init and __initdata attributes. When the driver would've been built as a module, all the missing clock-definitions (all are initdata) should've turned up as error in testing suggesting that the change wasn't at all - a clock driver is a very core component of soc bringup and making this able to be built as a module solely for enabling the soc vendor to add out of tree changes for Android implementations is not in our interest and also everything except a ramdisk won't probe without a clock controller. This is especially true when the changes aren't really tested and are merely added to move the mainline driver "out of the way".
