Randy Dunlap 7e45fc93dd PM: suspend: fix return value of __setup handler
[ Upstream commit 7a64ca17e4 ]

If an invalid option is given for "test_suspend=<option>", the entire
string is added to init's environment, so return 1 instead of 0 from
the __setup handler.

  Unknown kernel command line parameters "BOOT_IMAGE=/boot/bzImage-517rc5
    test_suspend=invalid"

and

 Run /sbin/init as init process
   with arguments:
     /sbin/init
   with environment:
     HOME=/
     TERM=linux
     BOOT_IMAGE=/boot/bzImage-517rc5
     test_suspend=invalid

Fixes: 2ce986892f ("PM / sleep: Enhance test_suspend option with repeat capability")
Fixes: 27ddcc6596 ("PM / sleep: Add state field to pm_states[] entries")
Fixes: a9d7052363 ("PM: Separate suspend to RAM functionality from core")
