Subject: draw: Avoid integer overflow converting pointers on 64bit archs.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2f24bc698412b4635422a52f9d7073ce7854dceb;p=mesa.git

draw: Avoid integer overflow converting pointers on 64bit archs.

Not really an error, as we only care for the lower 4 bits.
