Subject[PATCH] arm/bL_switcher: Use global define for masking hotplug transition switch action argument
Date
The action argument of the hotplug transition switch case is masked
with '0xf' to map CPU_XXX_FROZEN hotplug transition on corresponding
non frozen hotplug transitions. There is a global define
CPU_TASKS_FROZEN used as mask for frozen hotplug transitions.

Use '~CPU_TASKS_FROZEN' instead of '0xf'.
