4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bjorn Andersson bjorn.andersson@linaro.org
commit d1bf2d30728f310f72296b54f0651ecdb09cbb12 upstream.
Propagate the error of devfreq_add_device() in devm_devfreq_add_device() rather than statically returning ENOMEM. This makes it slightly faster to pinpoint the cause of a returned error.
