[PATCH 04/30] iio: magnetometer: hmc5843: 'hmc5843_pm_ops' is unused in 1 of 3 files including hmc5843_core.h

[Lee Jones]

We know that it's okay for 'hmc5843_pm_ops' to be unused here.

Fixes the following W=1 kernel build warning(s):

 In file included from include/linux/device.h:25,
 from include/linux/iio/iio.h:10,
 from drivers/iio/magnetometer/hmc5843_core.c:16:
