However, the caller ca8210_probe() then calls ca8210_remove(),\nwhere priv->clk is freed again in ca8210_unregister_ext_clock(). In\nthis case, a use-after-free may happen in the second time we call\nclk_unregister().\n\nFix this by removing the first clk_unregister(). Also, priv->clk could\nbe an error code on failure of clk_register_fixed_rate(). Use\nIS_ERR_OR_NULL to catch this case in ca8210_unregister_ext_clock()."
