More DeviceTree fixes for 4.0:
- Revert setting stdout-path as preferred console. This caused regressions in PowerMACs and other systems. - Yet another fix for stdout-path option parsing. - Fix error path handling in of_irq_parse_one -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJVCt/mAAoJEMhvYp4jgsXiVKUIALYn1mFKm/RJiTZ2inLeIL/9 Bl2U8y/kMT4NoNdKknIvdD8IngQuggl5WK7mpJo7LRZ3P9/t7msutzT8uwdn1868 6sDH4bIzR3/5x+ZFJubcv8UQXs8dbWiipXDGsemKUtUEF7Q4JBd9LCCEx+22WAnk f1uThOB8Jd8c7oLPu1wKSG0RSJYF4s1rjfDrjLkcg3QWAzEcThI/5ww5oeuFtee8 25xTXPgL4qTCRBsogse0339/pby8QUzFGdVHMGUEP/tjp82NfZ8+QxPOalLi103R kC6E9LTr85DgfxsqH5GVmA3pUHZfRb7OjLzoax5Dzf8kpYt8ta8sEw2+1uUadxY= =+ZiW -----END PGP SIGNATURE----- Merge tag 'devicetree-fixes-for-4.0-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux Pull more DeviceTree fixes vfom Rob Herring: - revert setting stdout-path as preferred console.
