Subject: Revert "egl: remove explicit config_id management from dri2_add_config()"
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=aeaf21ab3e6cb3e628ff0219461cbd06f3a99d34;p=mesa.git

Revert "egl: remove explicit config_id management from dri2_add_config()"

This reverts commit 3652d1d5942a857f225700d67ce2c900396982f2.

Self nack/reject on this one. The base.ConfigID is overwritten
immediately after we store the current value, thus one memcpy [further
down] the wrong value will be copied.
