2023-04-13clk: starfive: Avoid casting iomem pointersStephen Boyd
Let's use a wrapper struct for the auxiliary_device made in jh7110_reset_controller_register() so that we can stop casting iomem pointers. The casts trip up tools like sparse, and make for some awkward casts that are largely unnecessary. While we're here, change the allocation from devm and actually free the auxiliary_device memory in the release function. This avoids any use after free problems where the parent device driver is unbound from the device but the auxiliuary_device is still in use accessing devm freed memory.
