The name of 'struct pm_ops' suggests that it is related to the power management in general, but in fact it is only related to suspend. Moreover, its name should indicate what this structure is used for, so it seems reasonable to change it to 'struct platform_suspend_ops'. In that case, the name of the global variable of this type used by the PM core and the names of related functions should be changed accordingly. Signed-off-by: Rafael J.
