[PATCH 1/1] iwlwifi: mei: fix return value check in iwl_mei_dbgfs_register()

[Zhen Lei <thunder.leizhen@xxxxxxxxxx>]

Fix the incorrect return value check for debugfs_create_dir(), which
returns ERR_PTR(-ERROR) instead of NULL when it fails.

Fixes: 4ea7da5fad43 ("iwlwifi: mei: add debugfs hooks")
