Fixes for the v3.17 series:
- A largeish fix for the IRQ handling in the new Zynq driver. The quite verbose commit message gives the exact details. - Move some defines for gpiod flags outside an ifdef to make stub functions work again. - Various minor fixes that we can accept for -rc1. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJT+ZCiAAoJEEEQszewGV1zOZEQALkGrQacC9pZdhw93+wumj/d goA4B1VSwi+vlQ3DcF7oXbTcbaYfGu58ZAlShc9XhVINaWEkVfc1GnBCq9rsnjNh /rPaqDpqqBo7tfghjsMIZFdlNH151u/4rCAFMUB/STOAlUckSCiqWdxd7wMhAPlZ yLD5oKqm3mWu/PX2n334rkLb1UxT1vIniB3DgQRhUtrKeYarH9OpzJnWnCCmspCr GeVWpq4Z851fHMok5D76EbLL57JykTCC7VjHyK9jrmbjpMFX6+lYmWWMCOgUHypi zA5ZEL7PjhhrZlwTN5yn8QbuSfbmT14tTUP/OLtItE0CYjF1nheyxueKErHT+DP4 piLDZgdv79ZYBSbvfbpjeO5VLkZz3m7EAGp/0kWy89uGcwjVsk+zsDSDc0v09tTk hYRhu5/gc8zp3rd7v4DspSBbpxK+iI7uMzaGuv32AEdPvFzDVy4SJmRN/qTt/W9E KVAdk4OJdx7xb9ee9Z2OfdbteOt0zFQjmTIneZ0urlqOZCbvbFH4PvuPB4L81SCV XQ023OZqbBYb72Kz3Fw46NjMvRql3rkDph62oikEtfSKmSziMDY9z6bY42b0PCTq mSovoQduN06wRDy5VQA8H1h7VF3k8NXjTI2hMEV85VhxlCzhabukBf+HY37TQIhT pLQp0fwKmf8iZWtuF4Of =7iYA -----END PGP SIGNATURE----- Merge tag 'gpio-v3.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull gpio fixes from Linus Walleij: - a largeish fix for the IRQ handling in the new Zynq driver.
