[PATCH 0/9] iio: fix write_raw() return values and remove pm helpers

Hello,

This series fixes write_raw() return values and removes pm runtime
helpers in iio drivers, as Jonathan suggested when reviewing the
original iio patch [1].

Patches 1-2 fix write_raw() in isl29028 and tsl2583 to always return
zero on success. write_raw() returns the value of
pm_runtime_put_autosuspend(), which is 1 if the device is already
runtime suspended. In that case write() on the sysfs attribute returns
1 instead of the number of bytes written.

Patches 3-7 remove the pm runtime helpers in isl29028, tsl2583,
vcnl4035, vcnl4000 and rcar-gyroadc. Each helper just calls
pm_runtime_resume_and_get() or pm_runtime_put_autosuspend() depending
on its bool argument and adds no value.

Patches 8-9 are the remaining conditional return cleanups from the
original patch, generated by the Coccinelle script.
