cgroup could be throttled to a limit but when all cgroups cross high

cgroup could be assigned a limit, but doesn't dispatch enough IO, eg the

The suspend/resume functions were using dev_to_iio_dev() to get
the iio_dev. That only works on IIO dev's. Replace it with i2c
functions to get the correct iio_dev.

Hi folks,
while looking through driver initialization and removal functions, I noticed
that many drivers
call device_init_wakeup(dev, false) in the removal function. Given that the
driver is about
to be removed, that doesn't make much sense to me, especially since
device_wakeup_disable()
is ca
Declare dev_pm_ops structures as const as they are only stored in the pm
field of a vio_driver structure. This field is of type const, so
dev_pm_ops structures having similar properties can be declared const.
