* mfd: wm5102: Remove registers for output 3R from readable listCharles Keepax2015-04-091-3/+0
| | | | | | | | | The earpiece on 5102 is mono, thus there is no output 3R. Remove the registers associated with the unused right channel from the readable registers list. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: tps65010: Remove incorrect __exit markupsDmitry Torokhov2015-04-091-2/+2
| | | | | | | | | | | Even if bus is not hot-pluggable, the devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes.

* mfd: arizona: Correct type of gpio_defaultsCharles Keepax2015-03-301-1/+1
| | | | | | | | | | | | | gpio_defaults needs to be specified as an unsigned int rather than an int, because the intention of the DT binding is that all out of range values for a 16-bit register will cause the defaults to be used, however, if gpio_defaults is an int then values that are larger than INT_MAX will become negative numbers and be written out directly to the hardware. As no where in the code replies on gpio_defaults being an int, the simplest fix is to just change it to unsigned.

* mfd: core: Fix platform-device name collisionsJohan Hovold2015-03-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Since commit 6e3f62f0793e ("mfd: core: Fix platform-device id generation") we honour PLATFORM_DEVID_AUTO and PLATFORM_DEVID_NONE when registering mfd-devices. Unfortunately, some mfd-drivers rely on the old behaviour of generating platform-device ids by adding the cell id also to the special value of PLATFORM_DEVID_NONE. The resulting platform ids are not only used to generate device-unique names, but are also used instead of the cell id to identify cells when probing subdevices. These drivers should be updated to use PLATFORM_DEVID_AUTO, which would also allow more than one device to be registered without resorting to hacks (see for example wm831x), but lets fix the regression first by partially reverting the above mentioned commit with respect to PLATFORM_DEVID_NONE.
