2013-04-11misc: apds9802als: Fix suspend/resumeLars-Peter Clausen1-21/+4
The apds9802als driver implements runtime pm and at the same time uses the legacy pm callbacks for suspend and resume. This does not work since the i2c core wont look at the legacy pm callbacks if a driver has the 'pm' field set. This patch fixes it by moving over to dev_pm_ops for suspend/resume as well. Since both runtime pm and suspend/resume behave the same way this can easily be done using the UNIVERSAL_DEV_PM_OPS macro.

2013-04-10mei: nfc: Implement MEI bus opsSamuel Ortiz1-1/+169
The send ops for NFC builds the command header, updates the request id and then waits for an ACK. The recv ops check if it receives data or an ACK and in the latter case wakes the send ops up. The enable ops sends the NFC HECI connect command.

NFC ME device is exported through the MEI bus to be consumed by the NFC subsystem. NFC is represented by two mei clients: An info one and the actual NFC one. In order to properly build the ME id we first need to retrieve the firmware information from the info client and then disconnect from it.

2013-04-08mei: bus: Add device enabling and disabling APISamuel Ortiz2-12/+115
It should be left to the drivers to enable and disable the device on the MEI bus when e.g getting probed. For drivers to be able to safely call the enable and disable hooks, the mei_cl_ops must be set before it's probed and thus this should happen before registering the device on the MEI bus. Hence the mei_cl_add_device() prototype change.

2013-04-02extcon: arizona: Clear existing button reports before reporting new oneMark Brown1-0/+4
If the user moves directly from one button to another then we won't get a no buttons pressed event and will therefore end up reporting that two buttons are simultaneously pressed which isn't supported by the hardware.

2013-04-02extcon: arizona: Simplify HPDET based identificationMark Brown1-21/+25

2013-04-01cs5535-mfgpt: Add another reset methodRichard Weinberger1-4/+37
The CS5535/CS5536 MFGPT has no support to reset the device. The current method uses an undocumented bit but does not work on all devices. At least on my ALIX board it completely freezes the board. This new method tries to soft reset all timers by unconfiguring them. But this does not clear the RO setup register and therefore it has to be ignored while probing. Resetting the timers is not only needed on broken BIOSes also when kexec is used. Otherwise the new kernel will find preconfigured timers and odd things will happen.

2013-03-29rbd: don't zero-fill non-image object requestsAlex Elder1-17/+30
A result of ENOENT from a read request for an object that's part of an rbd image indicates that there is a hole in that portion of the image. Similarly, a short read for such an object indicates that the remainder of the read should be interpreted a full read with zeros filling out the end of the request. This behavior is not correct for objects that are not backing rbd image data. Currently rbd_img_obj_request_callback() assumes it should be done for all objects. Change rbd_img_obj_request_callback() so it only does this zeroing for image objects. Encapsulate that special handling in its own function. Add an assertion that the image object request is a bio request, since we assume that (and we currently don't support any other types). This resolves a problem identified here: http://tracker.ceph.com/issues/4559 The regression was introduced by bf0d5f503dc11d6314c0503591d258d60ee9c944.
