Pull GPIO fixes from Linus Walleij:
"Here is a bunch of GPIO fixes that I collected since -rc1, nothing
controversial, nothing special:
- fix a memory leak for GPIO hotplug.
- fix a signedness bug in the ACPI GPIO pin validation.
- driver fixes: Qualcomm SPMI and OMAP MPUIO IRQ issues"
* tag 'gpio-v4.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
gpio: omap: Fix regression for MPUIO interrupts
gpio: sysfs: fix memory leaks and device hotplug
pinctrl: qcom-spmi-gpio: Fix input value report
pinctrl: qcom-spmi-gpio: Fix output type configuration
gpiolib: change gpio pin from unsigned to signed in acpi callback
Read input buffer when input is enabled, not when it is
disabled. Also fix interpretation of the pmic_gpio_read()
return code, negative value means an error.

The zynq and qcom-spmi pinctrl drivers both use pin_config_item arrays
to provide extra interfaces in debugfs. This structure and the
PCONFDUMP macro are not defined if CONFIG_DEBUG_FS is turned off,
so we get build errors like:
pinctrl/qcom/pinctrl-spmi-gpio.c:139:37: error: array type has incomplete element type
static const struct pin_config_item pmic_conf_items[ARRAY_SIZE(pmic_gpio_bindings)] = {
^
pinctrl/qcom/pinctrl-spmi-gpio.c:140:2: error: implicit declaration of function 'PCONFDUMP' [-Werror=implicit-function-declaration]
PCONFDUMP(PMIC_GPIO_CONF_PULL_UP, "pull up strength", NULL, true),
^
pinctrl/qcom/pinctrl-spmi-gpio.c:139:37: warning: 'pmic_conf_items' defined but not used [-Wunused-variable]
static const struct pin_config_item pmic_conf_items[ARRAY_SIZE(pmic_gpio_bindings)] = {
Lacking any better idea to solve this nicely, this patch uses #ifdef
to hide the structures, just like the pinctrl core does.

New pin controllers such as ACPI-based may also have custom properties
to parse, and should be able to use generic pin config. Let's make the
code compile on !OF systems and rename members a bit to underscore it
is custom parameters and not necessarily DT parameters.
This fixes a build regression for x86_64 on the zeroday kernel builds.

Instead of the driver caring about implementation details like device
tree, just provide information about driver specific pinconf parameters
to pinconf-generic which takes care of parsing the DT.
