[PATCH v4 2/2] gpiolib: use dev_err() when gpiod_configure_flags failed

From: Andy Shevchenko
Date: Mon Mar 25 2024 - 13:57:16 EST


From: Peng Fan <peng.fan@xxxxxxx>

When gpio-ranges property was missed to be added in the gpio node,
using dev_err() to show an error message will helping to locate issues
easier.
