The Kconfig currently controlling compilation of this code is:
drivers/mfd/Kconfig:config AB8500_GPADC
drivers/mfd/Kconfig: bool "ST-Ericsson AB8500 GPADC driver"
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
Since module_init was not in use by this code, the init ordering
remains unchanged with this commit.
We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject
bogus threaded irq requests") threaded IRQs without a primary handler
need to be requested with IRQF_ONESHOT, otherwise the request will fail.
So pass the IRQF_ONESHOT flag in this case.
The semantic patch that makes this change is available
in scripts/coccinelle/misc/irqf_oneshot.cocci.

Other than that, a few minor driver core and debugfs changes. There

The "runtime idle" helper routine, rpm_idle(), currently ignores
return values from .runtime_idle() callbacks executed by it.
However, it turns out that many subsystems use
pm_generic_runtime_idle() which checks the return value of the
driver's callback and executes pm_runtime_suspend() for the device
unless that value is not 0. If that logic is moved to rpm_idle()
instead, pm_generic_runtime_idle() can be dropped and its users
will not need any .runtime_idle() callbacks any more.
Moreover, the PCI, SCSI, and SATA subsystems' .runtime_idle()
routines, pci_pm_runtime_idle(), scsi_runtime_idle(), and
ata_port_runtime_idle(), respectively, as well as a few drivers'
ones may be simplified if rpm_idle() calls rpm_suspend() after 0 has
been returned by the .runtime_idle() callback executed by it.
To reduce overall code bloat, make the changes described above.

Refactor the GPADC interface to avoid bugs in calling code:
- ab8500_gpadc_[convert|read_raw|ad_to_voltage] clarifies
each functions use case, *convert wraps *read_raw, and we

- Renamed gpadc function arguments from "input" to "channel" to
clarify use, so we don't get confused again.

properly. This is done by writing a number of special OTP
(one-time-programmable) registers at production. This patch
makes sure that these values are used to calibrate the returned
value from the GPADC so that it is correct.

This revamps the interface so that AB8500 GPADCs are fetched by
name. Probed GPADCs are added to a list and this list is searched
for a matching GPADC. This makes it possible to have multiple
AB8500 GPADC instances instead of it being a singleton, and
rids the need to keep a GPADC pointer around in the core AB8500
MFD struct.
Currently the match is made to the device name which is by default
numbered from the device instance such as "ab8500-gpadc.0" but
by using the .init_name field of the device a more intiutive
naming for the GPADC blocks can be achieved if desired.

This moves the ab8500-gpadc.h header down into the ab8500/
subdir in include/linux/mfd and fixes some whitespace in the
header in the process.
