This function call was found to be unnecessary as there is no equivalent platform_get_drvdata() call to access the private data of the driver. Also, the private data is defined in this driver, so there is no risk of it being accessed outside of this driver file. Reviewed-by:

fwnode_irq_get[_byname]() were changed to not return 0 anymore. The special error case where device-tree based IRQ mapping fails can't no longer be reliably detected from this return value. This yields a functional change in the driver where the mapping failure is treated as an error. The mapping failure can occur for example when the device-tree IRQ information translation call-back(s) (xlate) fail, IRQ domain is not found, IRQ type conflicts, etc. In most cases this indicates an error in the device-tree and special handling is not really required. One more thing to note is that ACPI APIs do not return zero for any failures so this special handling did only apply on device-tree based systems. Drop the special handling for DT mapping failures as these can no longer be separated from other errors at driver side. Change all failures in IRQ getting to be handled by continuing without the events instead of aborting the probe upon certain errors. Signed-off-by:

In function size_from_channelarray(), the return value 'bytes' is defined as int type. However, the calcution of 'bytes' in this function is designed to use the unsigned int type. So it is necessary to change 'bytes' type to unsigned int to avoid integer overflow. The size_from_channelarray() is called in main() function, its return value is directly multipled by 'buf_len' and then used as the malloc() parameter. The 'buf_len' is completely controllable by user, thus a multiplication overflow may occur here. This could allocate an unexpected small area. Signed-off-by:

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes. Signed-off-by:

There are devices (such as Murata IRS-D200 PIR proximity sensor) that check the data signal with a running period. I.e. for a specified time, they count the number of conditions that have occurred, and then signal if that is more than a specified amount. `IIO_EV_INFO_PERIOD` resets when the condition no longer is true and is therefore not suitable for these devices. Add a new `iio_event_info` `IIO_EV_INFO_RUNNING_PERIOD` that can be used as a running period. Also add a new `IIO_EV_INFO_RUNNING_COUNT` that can be used to specify the number of conditions that must occur during this running period. Signed-off-by:

Introduced bits: REG11[0] - selects Vref. 0 - calibration voltage, 1 - VDDA. txlx and later SoCs support VDDA or calibration voltage as Vref, but others support only calibration voltage. For newer platforms vendor uses VDDA as default. REG11[1] - reserved bit. g12a and later SoCs must write 1, others SoCs write 0. REG11[5] - Vref voltage. 0 - 0.9v, 1 - 1.8v. g12a and later SoCs must write 0, others SoCs write 1.
