2014-05-06mfd: tps65910: Fix possible invalid pointer dereference on ↵Krzysztof Kozlowski
regmap_add_irq_chip fail commit 483e2dfdbc94751430e41db9973985f5b054d322 upstream. Fixes: 4aab3fadad32 ("mfd: tps65910: Move interrupt implementation code to mfd file") tps65910_irq_init() sets 'tps65910->chip_irq' before calling regmap_add_irq_chip(). If the regmap_add_irq_chip() call fails in memory allocation of regmap_irq_chip_data members then: 1. The 'tps65910->chip_irq' will still hold some value 2. 'tps65910->irq_data' will be pointing to already freed memory (because regmap_add_irq_chip() will free it on error) This results in invalid memory access during driver remove because the tps65910_irq_exit() tests whether 'tps65910->chip_irq' is not zero.

2014-05-06mfd: max8997: Fix possible NULL pointer dereference on i2c_new_dummy errorKrzysztof Kozlowski
commit 97dc4ed3fa377ec91bb60ba98b70d645c2099384 upstream. During probe the driver allocates dummy I2C devices for RTC, haptic and MUIC with i2c_new_dummy() but it does not check the return value of this calls. In case of error (i2c_new_device(): memory allocation failure or I2C address cannot be used) this function returns NULL which is later used by i2c_unregister_device(). If i2c_new_dummy() fails for RTC, haptic or MUIC devices, fail also the probe for main MFD driver.

2013-05-17mfd: ab8500-core: Pass GPADC compatible string to MFD coreLee Jones
When booting with Device Tree enabled the MFD core uses each device's compatible string to find and allocate its associated of_node pointer, which in turn is passed to the driver via the platform_device struct. Without it, the driver won't be able to interrogate the Device Tree or locate suitable regulators and will most likely fail to probe.

2013-05-17mfd: ab8500-core: Use the correct driver name when enabling gpio/pinctrlLee Jones
When we're using Device Tree to enable GPIO drivers we're forced to be OS agnostic, thus we are forbidden use names like pinctrl as they are specific only to Linux, at least for the time being. However, when we are registering devices using internal systems such as MFD or platform registration, we can use such terminology. In this case we can and should use the platform device ID mechanism to specify which device we wish to utilise by detailing pinctrl-<device_name>. This patch fixes a regression that when booting with Device Tree enabled the ABx500 GPIO/Pinctrl devices are not probed.

2013-05-17mfd: ab8500: Pass AB8500 IRQ to debugfs code by resourceLinus Walleij
The AB8500 debug code which was merged in parallell with the multiplatform work incidentally introduced a new instance using the <mach/irqs.h> header which is now deleted, causing this build regression: drivers/mfd/ab8500-debugfs.c:95:23: fatal error: mach/irqs.h: No such file or directory compilation terminated. make[4]: *** [drivers/mfd/ab8500-debugfs.o] Error 1 The code most certainly never worked with device tree either since that does not rely on this kind of hard-coded interrupt numbers. Fix the problem at the root by passing it as a named resource from the ab8500-core driver. Use an untyped resource to stop the MFD core from remapping this IRQ relative to the AB8500 irqdomain.
