What this code does now is: If HAVE_CLK is selected, then there must be a clock for the device. Otherwise it will always pass. You want not to return error if a platform does have HAVE_CLK, but doesn't have a clock for sata? That would be simple to fix, but want to confirm if this is actually required. @Russell: Can we have your view also? -- viresh -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
