Mesa/u_st-dri-don-t-set-queryDmaBufFormats-queryDmaBufModif.patch

Author: Michal Srb <msrb@suse.com>
Subject: st/dri: don't set queryDmaBufFormats/queryDmaBufModifiers if the driver does not implement it
Patch-mainline: To be upstreamed
References: fdo#104926

This is equivalent to commit a65db0ad1c3, but for dri_kms_init_screen. Without
this gbm_dri_is_format_supported always returns false.
