2011-05-11PM / UNICORE32: Use struct syscore_ops instead of sysdevs for PMRafael J. Wysocki
Make some UNICORE32 architecture's code use struct syscore_ops objects for power management instead of sysdev classes and sysdevs. This simplifies the code and reduces the kernel's memory footprint. It also is necessary for removing sysdevs from the kernel entirely in the future. Signed-off-by: Rafael J.
