6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen Ni <nichen@xxxxxxxxxxx>
[ Upstream commit c04efbfd76d23157e64e6d6147518c187ab4233a ]
Because of the potential failure of the devm_kstrdup(), the
dl[i].codecs->name could be NULL.
Therefore, we need to check it and return -ENOMEM in order to transfer
the error.
