[PATCH -next] iio: accel: bma400: Switch to use dev_err_probe() helper

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

 



In the probe path, dev_err() can be replaced with dev_err_probe()
which will check if error code is -EPROBE_DEFER and prints the
error name. It also sets the defer probe reason which can be
checked later through debugfs. It's more simple in error path.
