X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f5fa68d9674156ddaafa12a058ccc93c8866d5f9;p=linux-beck.git

ARM: pm: force non-zero return value from __cpu_suspend when aborting

Ensure that the return value from __cpu_suspend is non-zero when
aborting.  Zero indicates a successful suspend occurred.
