Subject: When verifying the decoded header before decoding the object identifier
X-Git-Tag: v2.6.27-rc1~86^2
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=e2d2867ff8700d7431c68c089ff5f5ed7f2d5b40;p=linux-2.6-omap-h63xx.git

When verifying the decoded header before decoding the object identifier
(expecting a SPNEGO pseudo-mechanism oid), the test to verify it is a
primitive encoding is compared against the asn1 class.  Primitive is not a
class.  This brings check in line with similar check for krb/ntlmssp oid.
