Here is a set of GPIO fixes for the v4.9 kernel series: - Fix up off-by one and line offset validation, info leak to userspace, and reject invalid flags. Those are especially valuable hardening patches from Lars-Peter Clausen, all tagged for stable. - Fix module autoload for TS4800 and ATH79. - Correct the IRQ handler for MPC8xxx to use handle_level_irq() as it (A) reacts to edges not levels and (B) even implements .irq_ack(). We were missing IRQs here. - Fix the error path for acpi_dev_gpio_irq_get() - Fix a memory leak in the MXS driver. - Fix an annoying typo in the STMPE driver. - Put a dependency on sysfs to the mockup driver.
