* iio: humidity: hts221: Move symbol exports into IIO_HTS221 namespaceJonathan Cameron2022-06-151-0/+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.

* iio: humidity: hts221: Use EXPORT_SIMPLE_DEV_PM_OPS() to allow compiler to ↵Jonathan Cameron2022-06-151-1/+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. This removes the need for __maybe_unused markings etc. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Cc: Lorenzo Bianconi <lorenzo@kernel.org> Link: https://lore.kernel.org/r/20220220181522.541718-6-jic23@kernel.org Acked-by: Lorenzo Bianconi <lorenzo@kernel.org> Link: https://lore.kernel.org/r/20220604161223.461847-3-jic23@kernel.org
* iio: humidity: hts221: Drop unneeded casting when print error codeAndy Shevchenko2020-03-211-2/+2
| | | | | | | | Explicit casting in printf() usually shows that something is not okay. Here, we really don't need it by providing correct specifier. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
* iio: humidity: hts221: Make use of device propertiesAndy Shevchenko2020-03-211-1/+1
| | | | | | | | Device property API allows to gather device resources from different sources, such as ACPI. Convert the drivers to unleash the power of device property API.
