TRIVIAL: linux-3.15-rc5/arch/arm/mach-davinci/clock.c:413: pointless assignment to rate

[dcb]

[linux-3.15-rc5/arch/arm/mach-davinci/clock.c:413] -> [linux-3.15-rc5/arch/arm/mach-davinci/clock.c:
416]: (performance) Variable 'rate' is reassigned a value before the old one has been used.

Source code is

    unsigned long rate = clk->rate;

    ctrl = __raw_readl(pll->base + PLLCTL);
    rate = pll->input_rate = clk->parent->rate;

Suggest remove first assignment.
