2016-05-09mfd: arizona: Update device ordering to allow clean driver removalCharles Keepax1-5/+5
Since this commit: commit b9a8a271c38f ("mfd: make mfd_remove_devices() iterate in reverse order") The order in which the MFD children remove has been reversed, as our driver contains some dependencies between the devices we need to make some changes to ensure the driver unloads cleanly.

2016-04-19mfd: max77686: Use module_i2c_driver() instead of subsys initcallJavier Martinez Canillas1-12/+1
The driver's init and exit function don't do anything besides adding and deleting the I2C driver so the module_i2c_driver() macro could be used. Currently is not being used because the driver is initialized at subsys initcall level, claiming that this is done to allow consumers devices to use the resources provided by this driver. But dependencies are in DT so manual ordering of init calls is not necessary any more.

Commit d4edcf0d5695 ("mm/gup: Switch all callers of get_user_pages() to not pass tsk/mm") switched get_user_pages() callers to the simpler model where they no longer pass in the thread and mm pointer. But since then we've merged changes to a few drivers that re-introduce use of the old interface. Let's fix them up. They continued to work fine (thanks to the truly disgusting macros introduced in commit cde70140fed8: "mm/gup: Overload get_user_pages() functions"), but cause unnecessary build noise.
