5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexander Egorenkov <egorenar@xxxxxxxxxxxxx>
[ Upstream commit 7449ca87312a5b0390b765be65a126e6e5451026 ]
When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.
See commit 7dd541a3fb34 ("s390: no need to check return value of debugfs_create functions").
