Subject: i965: Don't cast the result of brw_prepare_vertices to an unsigned value.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2fa2dd3908c783663ca421134cde82e9b6a38a0d;p=mesa.git

i965: Don't cast the result of brw_prepare_vertices to an unsigned value.
      Negative value means other errors, not aperture overflow. fix bug #15752
