First set of IIO fixes for the 4.5 cycle.
This set comprises those not dependent on patches in the 4.5 merge cycle.
A second set will follow shortly with ones that are.
* core in kernel interfaces
- fix a possible NULL dereference that is a theoretical possibility
via odd usage of iio_channel_release. Pretty much a hardening of
the interface, but observed in the wild with the twl4030_charger
driver.
* acpi-als
- report the data as processed as it is in lux. This fixes a wrong
use of the IIO ABI. However, old _raw version retained to avoid
breaking any userspace in the wild that is relying on that (none
known but it doesn't hurt us much to retain it)
*
ade7753
- fix some error handling to avoid use of unitialized data.
* ltr501
- use a signed return type for ltr501_match_samp_freq so as to allow
returning of an error code.
* mcp4725
- set name field of struct iio_dev to ensure the sysfs name attribute
doesn't give NULL.
* mpl115
- temperature offset sign is wrong.
* stk8ba50
- IIO_TRIGGER dependency added
* ti_am335x_adc
- Label buffer as a software buffer. It's actually a hybrid of a
true hardware buffer feeding a kfifo, but the meaning of these fields
has changed a little recently and in this case it should be labeled
a software buffer ensure it is allowed to use the kfifo.
* vf610_adc
- HAS_IOMEM dependency
