The same source file already uses the same form of conditional expressions several lines above:

 > ret = pdata && pdata->enable ? pdata->enable(pdev) : 0;

 > dev->disable_platform = pdata ? pdata->disable : NULL;

Shall I use real if statement for my expression while keeping those as-is? This looks ... strange.
Or shall I convert all conditional expressions to if statements?
