[PATCH] clk: s2mps11: Fix double free corruption during driver unbind

After unbinding the driver memory was corrupted by double free of clk_lookup structure. This lead to OOPS when re-binding the driver again. The driver allocated memory for 'clk_lookup' with devm_kzalloc. During driver removal this memory was freed twice: once by clkdev_drop() and second by devm co
