[PATCH 1/6] gpio: xgene: remove redundant error message

From: Bartosz Golaszewski
Date: Wed Oct 02 2019 - 13:03:01 EST


From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

There's no need to emit an error message on probe failure unless we're
printing some meaningful info. Otherwise the core driver code will
inform us about a probe error.
