Merge tag '6.6-rc1-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6
Pull smb client fixes from Steve French: "Three small SMB3 client fixes, one to improve a null check and two minor cleanups" * tag '6.6-rc1-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6: smb3: fix some minor typos and repeated words smb3: correct places where ENOTSUPP is used instead of preferred EOPNOTSUPP smb3: move server check earlier when setting channel sequence number
