We missed the RFC tag. So, with this in mind we still have some minor
issues to fix and then we can move the code out of staging.
1) checkpatch.pl -- strict warnings
2) suspend/resume functions in hmc5843_core.c.
int hmc5843_common_suspend(struct device *dev)
{
return hmc5843_set_mode(iio_priv(dev_get_drvdata(dev)),
HMC5843_MODE_CONVERSION_CONTINUOUS);
}
int hmc5843_common_resume(struct device *dev)
{
return hmc5843_set_mode(iio_priv(dev_get_drvdata(dev)),
HMC5843_MODE_SLEEP);
}
I think the function names or implementations were swapped.
The device should go to sleep at suspend and back to continuous
mode on resume.
thanks,
Daniel.
