Merge tag 'pinctrl-fixes-v3.10-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin-control fixes from Linus Walleij: - Six patches fixing up the suspend/resume and wakeup handling of the Samsung and Exynos drivers. - Errorpath fixes for four different drivers. All on the probe() errorpath. - Make the debugfs code for pin config take the right mutex. * tag 'pinctrl-fixes-v3.10-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: pinctrl: pinconf: take the right mutex pinctrl: sunxi: fix error return code in sunxi_pinctrl_probe() pinctrl: exynos: Handle suspend/resume of GPIO EINT registers pinctrl: samsung: Allow per-bank SoC-specific private data pinctrl: samsung: Add support for SoC-specific suspend/resume callbacks pinctrl: Don't override the error code in probe error handling ARM: EXYNOS: Fix EINT wake-up mask configuration when pinctrl is used pinctrl: exynos: Add support for set_irq_wake of wake-up EINTs pinctrl: samsung: fix suspend/resume functionality
