4.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bjorn Andersson <bjorn.anders...@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.
Fixes: 8cd84092d35e ("PM / devfreq: Add resource-managed function for devfreq
device")
