d6441dc5ce mfd: twl6040: Disable and unprepare clk32k in twl6040_power() error path
The clk32k clock is prepared and enabled in twl6040_power() but the clock
is left enabled in case of an error while it should be disable/unprepared.

38fc2eec95 mfd: tps6105x: Remove linux/regulator/driver.h include
This driver makes no use of linux/regulator/driver.h which should only
be used by drivers implementing a regulator.  Since it's unlikely to

f83c218c17 mfd: arizona: Update device ordering to allow clean driver removal
Since this commit:

commit b9a8a271c3 ("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.

8a0aee4a7c mfd: max77686: Use module_i2c_driver() instead of subsys initcall
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.

Presumably this doesn't cause that many problems in real life because
normally we handle the IRQ.

adae28c59a mfd: syscon: Include errno.h from header
The syscon header uses the ENOTSUPP error constant, but doesn't
include the header that defines it. This causes a build error
after the imx pinctrl driver started using syscon:

include/linux/mfd/syscon.h: In function 'syscon_node_to_regmap':
include/linux/mfd/syscon.h:32:18: error: 'ENOTSUPP' undeclared (first use in this function)
  return ERR_PTR(-ENOTSUPP);
                  ^~~~~~~~

This adds the missing #include.

ee414de525 mfd: core: Fix ACPI child matching by _HID/_CID
If MDF child devices have separate ACPI nodes identified
by _HID/_CID, they will not be assigned the intended
ACPI companion.

acpi_match_device_ids will return 0 if a the child device
matches the _HID/_CID, so this patch changes the matching
condition to check for 0 on success.
