6.1-stable review patch.  If anyone has any objections, please let me know.

From: Anastasia Belova <abelova@xxxxxxxxxxxxx>

[ Upstream commit ff31ba19d732efb9aca3633935d71085e68d5076 ]

"host=" should start with ';' (as in cifs_get_spnego_key)
So its length should be 6.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
