I just ran the static analysis checker "cppcheck" over the
source code of the 3.10-rc6. It said

[linux-3.10-rc6/drivers/clk/sunxi/clk-sunxi.c:52]: (error) Memory leak: fixed
[linux-3.10-rc6/drivers/clk/sunxi/clk-sunxi.c:52]: (error) Memory leak: gate

Source code is

    if (of_property_read_u32(node, "clock-frequency", &rate))
        return;

Suggest new code

    if (of_property_read_u32(node, "clock-frequency", &rate)) {
        kfree(fixed);
        kfree(gate);
        return;
    }
