Merge tag 'gpio-v4.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO fixes from Linus Walleij:
"A bunch of GPIO fixes for the v4.7 series:
- Drop the lock before reading out the GPIO direction setting in
drivers supporting the .get_direction() callback: some of them may
be slowpath.
- Flush GPIO direction setting before locking a GPIO as an IRQ: some
electronics or other poking around in the registers behind our back
may have happened, so flush the direction status before trying to
lock the line for use by IRQs.
- Bail out silently when asked to perform operations on NULL GPIO
descriptors. That is what all the get_*_optional() is about: we
get optional GPIO handles, if they are not there, we get NULL.
- Handle compatible ioctl() correctly: we need to convert the ioctl()
pointer using compat_ptr() here like everyone else.
- Disable the broken .to_irq() on the LPC32xx platform. The whole
irqchip infrastructure was replaced in the last merge window, and a
new implementation will be needed"
