Subject: [PATCH] staging: rtlwifi: don't check the return value of debugfs_create_file
Git-commit: e206a0d47efa04b90eb5de5b9adee3c81bda9b03
Patch-mainline: v4.18-rc1
References: FATE#326887

We never did anything with the return value, and it does not matter if
the call succeeds or not (it's just debugging code), so don't even check
it.
