Merge tag 'iio-for-4.21a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-testing Jonathan writes: First set of new device support, features and cleanups for IIO in the 4.21 cycle Along with the headline feature of 5 new drivers, we have the substantial addition of auxilliary sensor support on the lsm6sdx parts for ST. There has also been a good set of staging cleanup in this period with more underway. An ever increasing number of devices supported with just a new ID which is a good sign that at least some manufacturers are continuing to stabilise their interfaces. New device support, * ad7124 - New driver supporting Analog Devices' ad7124-4 and ad7124-8 parts with the inevitable DT binding. * ad7949 - New driver supporting Analog Devices' ad7949, AD7682 and AD7689 ADCs. * rm3100 - New driver supporting PNIs RM3100 magnometer with bindings and vendor prefix. * ti-dac7311 - New driver supporting DAC7311, DAC6311 and DAC5311 TI DACs, with DT bindings. * vcnl5...

As one can see in a typedef at linux/types.h:103, s32 and int32_t are both a 32 bits signed integer. s32 is preferred because it is defined by the kernel maintainers and it prevents portability issues. Changed to meet checkpatch criteria. Signed-off-by:

ret = 0 indicates a case of no error but no data read from the bus which is an invalid case. This case doesn't ever happen in reality. It should perhaps be handled for correctness though. Signed-off-by:

adt7316_i2c_read function nowhere sets the data field. It is necessary to have an appropriate value for it. Hence, assign the value stored in 'ret' variable to data field. This is an ancient bug, and as no one seems to have noticed, probably no sense in applying it to stable. Signed-off-by:

The ad7124-4 and ad7124-8 are a family of 4 and 8 channel sigma-delta ADCs with 24-bit precision and reference. Three power modes are available which in turn affect the output data rate: * Full power: 9.38 SPS to 19,200 SPS * Mid power: 2.34 SPS to 4800 SPS * Low power: 1.17 SPS to 2400 SPS The ad7124-4 can be configured to have four differential inputs, while ad7124-8 can have 8. Moreover, ad7124 also supports per channel configuration. Each configuration consists of gain, reference source, output data rate and bipolar/unipolar configuration.
