This makes the driver use the data pointer added to the gpio_chip
to store a pointer to the state container instead of relying on
container_of().Cc: Feng Tang

As we want gpio_chip .get() calls to be able to return negative
error codes and propagate to drivers, we need to go over all
drivers and make sure their return values are clamped to [0,1].
We do this by using the ret = !!(val) design pattern.Cc: Feng Tang

This switches the two members of struct gpio_chip that were
defined as unsigned foo:1 to bool, because that is indeed what
they are. Switch all users in the gpio and pinctrl subsystems
to assign these values with true/false instead of 0/1. The
users outside these subsystems will survive since true/false
is 1/0, atleast we set some kind of more strict typing example.Signed-off-by: Linus Walleij

Otherwise, we return 0 in probe error paths when gpiochip_remove() returns 0.

gpio_chip.can_sleep is 0, but current code uses mutex in ioh_gpio_set,
ioh_gpio_get and ioh_gpio_direction_input functions.
Thus those functions are not callable from interrupt context.
This patch converts mutex into spinlock.Signed-off-by: Axel Lin

The __iomem annotation is to be used together with pointers used
in iowrite32() but not for pointers returned by kzalloc().
For more details see [1] and [2].This patch will remove the following sparse warning (i.e. when
copiling with "make C=1"):

Currently, GFP_KERNEL is used as parameter of irq_alloc_descs like below.
irq_base = irq_alloc_descs(-1, IOH_IRQ_BASE, num_ports[j],
GFP_KERNEL);This is not true.
So, this patch uses NUMA_NO_NODE not GFP_KERNEL.Reported-by: Dan Carpenter
