Pull GPIO fixes from Linus Walleij: "This is the first round of GPIO fixes for v4.3. Quite a lot of patches, but the influx of new stuff in the merge window was equally big, so I'm not surprised. - Return value checks and thus nicer errorpath for two drivers. - Make GPIO_RCAR arch neutral. - Propagate errors from GPIO chip ->get() vtable call. It turned out these can actually fail sometimes, especially on slowpath controllers doing I2C traffic and similar. - Update documentation to be in sync with the massive changes in the v4.3 merge window, phew. - Handle deferred probe properly in the OMAP driver. - Get rid of surplus MODULE_ALIAS() from sx150x" * tag 'gpio-v4.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: gpio: omap: Fix GPIO numbering for deferred probe Documentation: gpio: Explain that <function>-gpio is also supported gpio: omap: Fix gpiochip_add() handling for deferred probe gpio: sx150x: Remove unnecessary MODULE_ALIAS() Documentation: gpio: board: describe the con_id parameter Documentation: gpio: board: add flags parameter to gpiod_get*() functions gpio: Propagate errors from chip->get() gpio: rcar: GPIO_RCAR doesn't relate to ARM gpio: mxs: need to check return value of irq_alloc_generic_chip gpio: mxc: need to check return value of irq_alloc_generic_chip
