To: gregkh@xxxxxxxxxxxxxxxxxxx, stable@xxxxxxxxxxxxxxx

Message-ID: <20231218153454.8090-108-linkinjeon@xxxxxxxxxx>
From: Lu Hongfei <luhongfei@xxxxxxxx>
[ Upstream commit ccb5889af97c03c67a83fcd649602034578c0d61 ]
The return value of ksmbd_vfs_query_maximal_access is meaningless,
it is better to modify it to void.
