iio: temperature: ltc2983: Make use of device properties

2022-04-04T08:11:24Z

Convert the module to be property provider agnostic and allow it to be used on non-OF platforms. The conversion slightly changes the logic behind property reading for the configuration values. Original code allocates just as much memory as needed. Then for each separate 32- or 64-bit value it reads it from the property and converts to a raw one which will be fed to the sensor. In the new code we allocate the amount of memory needed to retrieve all values at once from the property and then convert them as required.

iio: temperature: ltc2983: Use single error path to put OF node

2022-04-04T08:11:24Z

There are several, possibly copied'n'pasted, places in the functions, where OF node is put and error returned directly, while the common exit point exists. Unify all these cases to use a single error path.

In a couple of messages the constants, which have their definitions, are hard coded into the message text. Unhardcode them. While at it, add a trailing \n where it's currently missing.

iio:temperature:mlx90614: Switch from CONFIG_PM* guards to pm_ptr() etc

2022-02-18T11:46:04Z

Letting the compiler remove these functions when the kernel is built without one or more of CONFIG_PM/CONFIG_PM_SLEEP support is simpler and less error prone than the use of #ifdef based config guards. Removing instances of this approach from IIO also stops them being copied into new drivers.
