| Subject: PM / devfreq: Propagate error from devfreq_add_device() |
| |
| 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. |
| |
| Fixes: 8cd84092d35e ("PM / devfreq: Add resource-managed function for devfreq device") |
