[-next,3/5] Input: pwm-beeper - Switch to use dev_err_probe() helper

Commit Message

Yang Yingliang Sept. 20, 2022, 3:36 p.m. UTC

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.
