[PATCH -next 1/5] Input: da7280 - Switch to use dev_err_probe() helper

[Yang Yingliang <yangyingliang@huawei.com>]

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.
