Subject: drm/i915: Introduce for_each_dbuf_slice_in_mask macro
Git-commit: 8435576b3f69451127fd6149affb94741a82293e
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
We quite often need now to iterate only particular dbuf slices
in mask, whether they are active or related to particular crtc.
v2: - Minor code refactoring
v3: - Use enum for max slices instead of macro
Let's make our life a bit easier and use a macro for that.
