Subject: MIPS: Add missing FROZEN hotplug notifier transitions
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=a8c5ddf08f1f7e587240c44f82f4762bd37df1f3;p=openwrt%2Fstaging%2Fblogic.git

MIPS: Add missing FROZEN hotplug notifier transitions

The corresponding FROZEN hotplug notifier transitions used on
suspend/resume are ignored. Therefore the switch case action argument
is masked with the frozen hotplug notifier transition mask.
