Calling dev_set_name with a single paramter causes it to be handled as a
format string. Many callers are passing potentially dynamic string
content, so use "%s" in those cases to avoid any potential accidents,
including wrappers like device_create*() and bdi_register().

Pull removal of GENERIC_GPIO from Grant Likely:
"GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any
valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it
is possible to do so which has been causing confusion and breakage.
This branch does the work to completely eliminate GENERIC_GPIO."

This is small fixes for extcon driver.
MAX77693 extcon driver
- Add 'static' keryword to internal data structure
- Fix return value using 'ret' instead of hardcoding

Return the value obtained from the function instead of hardcoding.

extcon: arizona: Updates for v3.10
There's a bunch of different things in this series, I can split them out
if need be:
- Support for configuring the button detection circuit to reflect the
accessories supplied with the system.
- Improvements in the HPDET based detection scheme.
- Additional robustness against more pathological use cases.
- A few small standalone fixes.
Help mitigate against mechanical bounce during the initial detection by
allowing the configuration of an additional debounce on top of that the
hardware does during the initial phase of microphone detection operation.

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.
Make sure we clear any existing button reports before reporting any new
ones.

In pathological cases the microphone detection may fail to report, for
example due to a failure to get a stable measurement. Provide a timeout
to cover such cases.

Rather than measuring both HP channels we can simply directly measure the
microphone impedance and then rely on MICDET for final confirmation of the
presence of a suitable microphone. This improves the overall performance
of the identification process.

This extra check makes the procedure take longer and is of marginal use
in identification so do not execute it.

Sometimes we can trigger measurements early if contacts are shorted during
a slow insertion. As well as debouncing add further robustness by retrying
if we get a high impedance measurement for headphones as this can indicate
that the headphones were not yet connected.

Occasionally we can trigger an interrupt before we have completed
impedance measurement, although the valid bit will still be set. This
patch spins reading the impedance value until a valid value is seen.

In cases where we see a brief (dis)connection of the jack detection signals
we may see a noop jack insertion or removal where the jack has returned to
the original state by the time the interrupt is serviced. Suppress these
events in order to save work and avoid confusing the rest of the code.

There is no need to do this as HPDET identification will cause MICBIAS to
