Subject: mesa/gdi: remove wmesa_set_renderbuffer_funcs() function
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4a1c66059957f8650afb73f9c0f982e4ae7b8200;p=mesa.git

mesa/gdi: remove wmesa_set_renderbuffer_funcs() function

The code is no longer relevant.
Note: this driver is probably broken now.  There's no implementation
of ctx->Driver.Map/UnmapRenderbuffer().
