[PATCH 2/2] iio: health: afe4404: Make use of the helper function dev_err_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When possible use dev_err_probe help to properly deal with the
PROBE_DEFER error, the benefit is that DEFER issue will be logged
in the devices_deferred debugfs file.
Using dev_err_probe() can reduce code size, and the error value
gets printed.
