[Buildroot] [PATCH 1/1] ti-gfx: build with GCC 4.8

Peter, All,

> In older kernels clk_disable() is a void function.

Not only in older kernels, but in recent kernels, too.

For example, in v3.14-rc4:

    $ git grep 'void clk_disable' include
    include/linux/clk.h:void clk_disable(struct clk *clk);

But why did you change clk_enable too? As far as I can see, it always
returned an int, for as long as it existed. Eg. in v2.6.19:

    $ git grep 'int clk_enable' include
    include/linux/clk.h:int clk_enable(struct clk *clk);
