Subject: mesa/main: Don't use ONCE_FLAG_INIT as a r-value.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9fed4f9bf5146af1fcd093422b39353845f2267a;p=mesa.git

mesa/main: Don't use ONCE_FLAG_INIT as a r-value.

It should only be used as an initializer expression.

Trivial, and fixes Windows builds.

Nevertheless, overwriting an once_flag like this seems dangerous and
should be revised.
