From: Tobias Jakobi <[email protected]> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know.
=============== commit 14a21e7ba8cf6eab968310c92ca19a00f13ce3d9 upstream. Writing the currently set governor into sysfs currently seems to fail. Fix this by setting the return code to zero before leaving governor_store().
