Merge tag 'gpio-v4.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO fixes from Linus Walleij:
"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"
