clk: zynqmp: Fix memory allocation in zynqmp_clk_setup
Fix memory allocation and use struct_size() in kzalloc(). This also fixes the allocation size to be correct, and smaller, because before we were allocating a bunch of sizeof(struct clk_hw_onecell_data) structures for each struct clk_hw we needed. Fixes: 3fde0e16d016 ("drivers: clk: Add ZynqMP clock driver") Cc: stable@vger.kernel.org Signed-off-by: Gustavo A. R.
