H A Dextcon-adc-jack.cbc84cff2 Sun May 10 04:53:03 CDT 2020 Christophe JAILLET <christophe.jaillet@wanadoo.fr> extcon: adc-jack: Fix an error handling path in 'adc_jack_probe()'

In some error handling paths, a call to 'iio_channel_get()' is not balanced
by a corresponding call to 'iio_channel_release()'.

This can be achieved easily by using the devm_ variant of
'iio_channel_get()'.

This has the extra benefit to simplify the remove function.

External connector devices that decides connection information based on
ADC values may use adc-jack device driver. The user simply needs to
provide a table of adc range and connection states. Then, extcon
framework will automatically notify others.

Changes in V1:
added Lars-Peter Clausen suggested changes:
Using macros to get rid of boiler plate code such as devm_kzalloc
and module_platform_driver.Other changes suggested are related to
coding guidelines.

Changes in V2:
Removed some unnecessary checks and changed the way we are un-regitering
extcon and freeing the irq while removing.

Changes in V3:
Renamed the files to comply with extcon naming.

Changes in V4:
Added the cancel_work_sync during removing of driver.

Changes in V5:
Added the dependency of IIO in Kconfig.

Changes in V6:
Some nitpicks related to naming.

Changes in this version:
V6 patch version patch broke the build:
ERROR: "extcon_cable_name" [drivers/extcon/extcon-adc-jack.ko] undefined!

Fixed it in this version.
