Subject: iio: gyro: bmg160: only set power state if PM_RUNTIME is defined
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ef1c6b23355b70356ca18c0d4c39b25dfbd7be02;p=linux-beck.git

iio: gyro: bmg160: only set power state if PM_RUNTIME is defined

When CONFIG_PM_RUNTIME is not defined and bmg160 tries to power
off the device, bmg160_set_power_state will call pm_runtime_put_autosuspend,
which is not implemented (wil return -ENOSYS).

Only call bmg160_set_power_state when CONFIG_PM_RUNTIME is defined.
