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.

Avoid unnecessary pollution of the global symbol namespace by moving library functions in to a specific namespace and import that into the drivers that make use of the functions. For more info: https://lwn.net/Articles/760045/Signed-off-by:

These new functions move the burden of removing unused code when CONFIG_PM_SLEEP is not defined onto the compiler rather than requiring the use of CONFIG_PM guards and similar. Signed-off-by:

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. This removes the need for __maybe_unused markings etc. Signed-off-by:

Jonathan Cameron authored
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. Signed-off-by:

There is no reason to include OF as we only need to forward declare 'of_phandle_args'. Previously, some drivers were actually relying on this for some headers (those were already fixed). Signed-off-by:

Do not trust the fact that iio.h includes of.h which in turn includes all the headers we are relying on. The ultimate goal is to actually drop of.h from iio.h. Signed-off-by:
