| Subject: PM / QoS: Set cpu_dma_pm_qos->name |
| |
| Since commit 4a31a334, the name of this misc device is not initialized, |
| which leads to a funny device named /dev/(null) being created and |
| /proc/misc containing an entry with just a number but no name. The latter |
| leads to complaints by cryptsetup, which caused me to investigate this |
| matter. |
