Making Sass Linear Gradient Mixins Behave in IE

I wrote this fairly straightforward cross-browser linear gradient mixin:

@mixin gradient($from-color, $to-color) {
	background-color: mix($from-color, $to-color); /* Fallback */
	background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, from($from-color), to($to-color));
	background-image: -webkit-linear-gradient(top, $from-color, $to-color); 
	background-image:    -moz-linear-gradient(top, $from-color, $to-color);
	background-image:     -ms-linear-gradient(top, $from-color, $to-color);
	background-image: -o-linear-gradient(top, $from-color, $to-color);
