No upstream commit exists for this patch. Remove kfree(&vi->smb_vol), since &vi->smb_vol is a pointer to an area inside the allocated memory. The issue was fixed on the way by upstream commit 837e3a1bbfdc ("cifs: rename dup_vol to smb3_fs_context_dup and move it into fs_context.c") but this commit is not material for stable branches. Found by Linux Verification Center (linuxtesting.org) with SVACE.
