2022-06-15iio: adc: meson_saradc: Don't attach managed resource to IIO device objectAndy Shevchenko
It feels wrong and actually inconsistent to attach managed resources to the IIO device object, which is child of the physical device object. The rest of the ->probe() calls do that against physical device. Resolve this by reassigning managed resources to the physical device object.

2022-06-15iio: at91-sama5d2: Limit requested watermark value to hwfifo sizePaul Cercueil
Instead of returning an error if the watermark value is too high, which the core will silently ignore anyway, limit the value to the hardware FIFO size; a lower-than-requested value is still better than using the default, which is usually 1.

remove dead code. If CONFIG_PM_SLEEP is not defined using EXPORT_SIMPLE_DEV_PM_OPS() in conjunction with pm_sleep_ptr() allows the compiler to remove the unused code and data.

2022-06-15iio:accel:kxsd9: Switch from CONFIG_PM guards to pm_ptr() etcJonathan Cameron
Letting the compiler remove these functions when the kernel is built without CONFIG_PM 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.
