2018-10-21staging: iio: ad7816: Switch to the gpio descriptor interfaceNishad Kamdar1-46/+34
Use the gpiod interface for rdwr_pin, convert_pin and busy_pin instead of the deprecated old non-descriptor interface. Note that Phil Reid identified that some of this code would never have worked. A follow up patch can fix that as this is just a direct change of interface.

2018-10-14iio: dpot-dac: mark expected switch fall-through with text GCC expects.Gustavo A. R. Silva1-2/+2
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that in this particular case, I replaced "...and fall through." with the specific string "fall through", which is what GCC is expecting to find thus supressing this false positive. As Peter has observed this breaks the nice English flow, which is less than ideal, but short of teaching GCC to read English, there isn't a lot that we can do about it.

2018-10-07iio: ssp_sensors: don't manually free devm managed resourcesUwe Kleine-König1-14/+6
The charme of devm_* functions is that you don't need to care about them in the error path. In this case it is valid to just return NULL which makes the device fail to probe and then the two gpios and the allocated memory are freed automatically by the driver core.
