fs/cifs: suppress a string overflow warning
[ Upstream commit bcfb84a996f6fa90b5e6e2954b2accb7a4711097 ]
A powerpc build of cifs with gcc v8.2.0 produces this warning:
fs/cifs/cifssmb.c: In function ‘CIFSSMBNegotiate’:
fs/cifs/cifssmb.c:605:3: warning: ‘strncpy’ writing 16 bytes into a region of size 1 overflows the destination [-Wstringop-overflow=]
strncpy(pSMB->DialectsArray+count, protocols[i].name, 16);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Since we are already doing a strlen() on the source, change the strncpy
to a memcpy().
