Prepare for re-enabling -Wunused-but-set-variable.
The intel_dp variable has been unused since commit ef79fafe9dae
("drm/i915: Eliminate intel_dp.regs.dp_tp_{ctl,status}").

Prepare for re-enabling -Wunused-but-set-variable.
The vbp is not used for anything in the readout, as we get
e.g. crtc_vtotal from BXT_MIPI_TRANS_VTOTAL.

Prepare for re-enabling -Wunused-but-set-variable.
Apparently sseu is leftover from commit 9a92732f040a ("drm/i915/gt: Add
general DSS steering iterator to intel_gt_mcr").

A next patch can make eb_unbind() a void function.

Prepare for re-enabling -Wunused-but-set-variable.
The variable 'c' appears unused, but I'm not sure what should be done
with it. Annotate it with __maybe_unused.

Yes... it's only initialized... maybe we need to come out with a
version of __get_user() that doesn't need 'c'. I think the
__maybe_unused fits good here.

Prepare for re-enabling -Wunused-but-set-variable.
The variable is indeed 'unused' as the name suggests, but we can't just
drop it because i915_vma_unbind_unlocked() is annotated
__must_check. Apparently the selftest does not really need to check the
value.

Prepare for re-enabling -Wunused-but-set-variable.
for_each_new_intel_plane_in_state() requires passing in a struct
intel_plane_state pointer, which it uses, but in many places this leads
to warning about unused but set variables. Annotate them with
__maybe_unused.

Prepare for re-enabling -Wunused-but-set-variable.
for_each_new_intel_crtc_in_state() requires passing in a struct
intel_crtc_state pointer, which it uses, but in a few places this leads
to warning about unused but set variables. Annotate them with
__maybe_unused.

Frankly I'm not sure what to do with these. Maybe the variables should

I sent an patch to fix the warnings. You can include that one in the
series. Zhenyu, can you give an rb?

W=1 enables -Wunused-but-set-variable. We disabled it locally in i915
Makefile as we were hitting a bunch of warnings. See commit 6a05d2900464
("drm/i915: Disable unused-but-set compiler warning").
With the issues fixed or annotated with __maybe_unused, re-enable the
warning not only in W=1 but also locally as part of i915 build.
