6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shyam Prasad N <sprasad@xxxxxxxxxxxxx>
commit 9599d59eb8fc0c0fd9480c4f22901533d08965ee upstream.
The only reason why cifs_sb gets passed today to cifs_try_adding_channels
is to pass the local_nls field for the new channels and binding session.
However, the ses struct already has local_nls field that is setup during
the first cifs_setup_session. So there is no need to pass cifs_sb.
This change removes cifs_sb from the arg list for this and the functions
that it calls and uses ses->local_nls instead.
