changes since v2:
- add more comments on enter_s2idle to explain why it is necessary to return
int even if its return value is never used.
changes since v1:
- add more description in commit message.
*** BLURB HERE ***
Neal Liu (1):
cpuidle: change enter_s2idle() prototype
drivers/acpi
_driver *drv,
int index); };
In this case, either enter() or enter_s2idle() would cause CFI check
failed since they use same callee.
Align function prototype of enter() since it needs return value for
some use cases. The return value of enter_s2idle() is no
need currently.
