Subject: linux-next: build failure after merge of the drm tree

Hi all,

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

drivers/gpu/drm/i915/gt/intel_mocs.c: In function 'get_mocs_settings':
drivers/gpu/drm/i915/gt/intel_mocs.c:363:22: error: 'GEN11_NUM_MOCS_ENTRIES' undeclared (first use in this function); did you mean 'GEN9_NUM_MOCS_ENTRIES'?
  363 |   table->n_entries = GEN11_NUM_MOCS_ENTRIES;
      |                      ^~~~~~~~~~~~~~~~~~~~~~
      |                      GEN9_NUM_MOCS_ENTRIES
drivers/gpu/drm/i915/gt/intel_mocs.c:363:22: note: each undeclared identifier is reported only once for each function it appears in

Caused by commit

  2606b269234b ("drm/i915/dg1: Define MOCS table for DG1")

interacting with commit

  7c5c15dffe1e ("drm/i915/gt: Declare gen9 has 64 mocs entries!")

from the drm-intel-fixes tree.

I have applied the following merge fix patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Wed, 9 Dec 2020 12:47:45 +1100
Subject: [PATCH] fixup for "drm/i915/gt: Declare gen9 has 64 mocs entries!"
