merf.  I get the following warning when building kirkwood_defconfig:

arch/arm/mach-kirkwood/pm.c: In function 'kirkwood_pm_init':
arch/arm/mach-kirkwood/pm.c:73:2: warning: 'return' with a value, in function returning void [enabled by default]

I've amended the patch as below and pushed it to mvebu/fixes

thx,

Jason.

    ARM: kirkwood: kirkwood_pm_init() should return void
    
    This function was originally meant to return void as declared in the
    common.h header. Fix it and include the header to catch these errors
    in the future.
    
    [jac] removed 'return 0;' to clear this warning:
    
      arch/arm/mach-kirkwood/pm.c: In function 'kirkwood_pm_init':
      arch/arm/mach-kirkwood/pm.c:73:2: warning: 'return' with a value, in function returning void [enabled by default]
