and it can be found in the queue-6.1 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree,
please let <stable@xxxxxxxxxxxxxxx> know about it.
commit c748cc3312f1332782e34d7a26c0a4204c7728e9

crypto: hisilicon/qm - split a debugfs.c from qm
[ Upstream commit 94476b2b6d60bc926a585ae62e1bf69bd22c1dff ]
Considering that the qm feature and debugfs feature are independent.
The code related to debugfs is getting larger and larger. It should be
separate as a debugfs file. So move some debugfs code to new file from
qm file. The qm code logic is not modified. And maintainability is
enhanced.
