The AD5600 is a single channel, 16-bit resolution, voltage output digital to analog converter (DAC). The AD5600 uses a 3-wire SPI interface. It is part of the AD5541 family of DACs. The ad5446 IIO driver implements support for some of these DACs (in the AD5441 family), so the change is a simple entry in this driver.

veml6030 is an ambient light sensor from Vishay semiconductors. It has 16-bit resolution, supports both ambient light measurement and white channel which is more responsive to wider wavelength spectrum. It has flexible power saving, integration time and gain options. Communication with host is over I2C.

The inline read functions in the ADIS library don't check the return value of the `adis_read_reg()` function and assign the value of `tmp` regardless. Fix this by checking if return value is zero and only then assigning the value of `tmp`. No known case of the callers of this function incorrectly using the value, but best to stop any potential risk here. Not suitable for stable due to no known actual bugs caused by this issue.

This was also caught by the `-Wmaybe-uninitialized` warning, which (ironically as-is) it makes quite a lot of sense to do for this. The code that actually calls this function will fail to copy on the uninitialized value. Hence, patch does not need to go into stable.

This was found only after the whole thing with the inline functions, but the compiler actually found something. The value of the `bias` (in adis16480_get_calibbias()) should only be set if the read operation was successful. No actual known problem occurs as users of this function all ultimately check the return value. Hence probably not stable material.

The ADIS library functions return zero on success, and negative values for error. Positive values aren't returned, but we only care about the success value (which is zero). This change is mostly needed so that the compiler won't make any inferences about some about values being potentially un-initialized. This only triggers after making some functions inline, because the compiler can better follow return paths.

This change moves iio_triggered_buffer_postenable() to be called first. It adds iio_triggered_buffer_predisable() on the error paths of the postenable hook. For the predisable hook, some code-paths have been changed to make sure that the iio_triggered_buffer_predisable() hook gets called in case there is an error before it.

At a slight footprint cost (24 vs 32 bytes), mutexes are more optimal than semaphores; it's also a nicer interface for mutual exclusion, which is why they are encouraged over binary semaphores, when possible. For both v_sem and z_sem, their semantics imply traditional lock ownership; that is, the lock owner is the same for both lock/unlock operations. Therefore it is safe to convert.

Merge tag 'iio-for-5.5b' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Second set of IIO + counter new device support, features etc for the 5.5 cycle. Note two merge commits in here, both for immutable branches based of 5.4-rc1. 1. Ti eqep driver because of some file moves in precursor patches. I suspect no one else will pull this one. 2. ab8500 refactor as changes in power supply, hwmon and mfd trees. This may come via numerous trees as well as IIO. Counter subsystem related * ti eqep - New device support with bindings. - Includes prior file move to reflect more general use of ti-pwmss. * Counter core - simplify count_read and count_write callbacks + document change. - fix a typo in docs.
