For the function of platform_get_irq(), the example in platform.c is
* int irq = platform_get_irq(pdev, 0);
* if (irq < 0)
* return irq;
the return value of zero is unnecessary to check, so make the right
check and simplify code.
Note that platform_get_irq() is documented as never returning 0
so this is a minor optmization rather than a fix.
