Patch "clk: core: Copy connection id" made it so that the connector id (con_id) is kstrdup_const'ed to cater to drivers that pass non- constant connection ids. The patch added the corresponding kfree_const to __clk_free_clk, but struct clk's can be freed also via __clk_put. Add the kfree_const

More explanation: If there is a machine with 10 nodes, and memory size in each node is 20G. Then 'kernelcore=100G' will set last 10G memory in each node as ZONE_MOVABLE. But if KASLR put kernel to 19G position of first node, the regions can not be offlined. So we should set the last 1G of first
