Subject: PM / QoS: Set cpu_dma_pm_qos->name
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a6f05b97d1ba87326bd96f3da9fef994830d6994;p=openwrt%2Fstaging%2Fblogic.git

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.
