Subject: glx: fix length of GLXGetFBConfigsSGIX
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cbe9fc12a64c3ae89fd1b20e9e165aa4b76293a5;p=mesa.git

glx: fix length of GLXGetFBConfigsSGIX

The extra length is the size of the request *minus* the size of the
VendorPrivate header, not the addition.

NOTE: This is a candidate for the 7.9 and 7.10 branches
