Added Lorenzo and Catalin.
this should be handled in the arm_cpuidle_read_ops function.
Thanks for reviewing. After some consideration, I think this patch isn't correct
There may be platforms which doesn't need the init member at all, although
currently I don't see such platforms in mainline, So I'll drop this patch
and send out one v2 only does the optimization.
There is an inconsistency between ARM and ARM64. The 'cpu_get_ops', the
arm_cpuidle_read_ops from the ARM64 side, returns -EOPNOTSUPP when the
init function is not there for cpuidle.
arm64's arm_cpuidle_init() returns -EOPNOTSUPP if init callback isn't defined
I don't think it is a problem, but as ARM/ARM64 are sharing the same
cpuidle-arm.c driver it would make sense to unify the behavior between
yes, agree with you. From "unify" point of view, could I move back the suspend
callback check and init callback check into arm_cpuidle_init() for arm as V1 does?
