Hi all,

After merging the drm-intel-fixes tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/gpu/drm/i915/gt/intel_lrc.c: In function 'gen12_emit_fini_breadcrumb':
drivers/gpu/drm/i915/gt/intel_lrc.c:4998:31: error: implicit declaration of function '__gen8_emit_flush_dw'; did you mean 'gen8_emit_flush'? [-Werror=implicit-function-declaration]
 4998 |  cs = emit_xcs_breadcrumb(rq, __gen8_emit_flush_dw(cs, 0, 0, 0));

Caused by commit

  c94d65d2ff6d ("drm/i915/gt: Flush xcs before tgl breadcrumbs")

I have reverted that commit for today.
