Pull GPIO fixes from Linus Walleij: "Here us a bunch of patches for the v3.13 series. Most important stuff is related to fixes and documentation for the new GPIO descriptor API. If the diffstat is scary you'll notice most of it is to Documentation/*: - A big slew of documentation for the gpiod transition that happened in the merge window, no semantic effect, but we should provide proper documentation with the new API. - Fix flags related to the new API. - Fix to the find_chip_by_name() lookup function related to the new API. - Fix of_find_gpio() when not using device tree. - Bug fix for the TB10x direction setting. - Error path fixes from Dan Carpenter. - Nasty IRQdomain bug relating to taking an unitialized spinlock. - Minor fixes here and there" * tag 'gpio-v3.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: gpio: bcm281xx: Fix return value of bcm_kona_gpio_get() gpio: pl061: move irqdomain initialization gpio: ucb1400: Add MODULE_ALIAS gpiolib: fix of_find_gpio() when OF not defined gpio: fix memory leak in error path gpio: rcar: NULL dereference on error in probe() gpio: msm: make msm_gpio.summary_irq signed for error handling gpio: mvebu: make mvchip->irqbase signed for error handling gpiolib: use dedicated flags for GPIO properties gpiolib: fix find_chip_by_name() Documentation: gpiolib: document new interface gpio: tb10x: Set output value before setting direction to output
