[PATCH v3 1/2] regulator: core: Fix more error checking for debugfs_create_dir()

From: Geert Uytterhoeven
Date: Thu May 25 2023 - 07:14:08 EST


In case of failure, debugfs_create_dir() does not return NULL, but an
error pointer. Most incorrect error checks were fixed, but the one in
create_regulator() was forgotten.

Fix the remaining error check.
