Subject: egl_dri2: Fix a snprintf warning.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7e7c1ba40b6e10b7d38490e7f3252dbebb3a3a72;p=mesa.git

egl_dri2: Fix a snprintf warning.

The subtraction between two pointers has type unsigned int (only on
x86-64?), while the format string expects an int.
