5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>
[ Upstream commit 6252f47b78031979ad919f971dc8468b893488bd ]
When dev_set_name() fails, zcdn_create() doesn't free the newly
allocated resources. Do it.
Fixes: 00fab2350e6b ("s390/zcrypt: multiple zcrypt device nodes support")
