Currently if stream->signal is neither SIGNAL_TYPE_DISPLAY_PORT_MST or
SIGNAL_TYPE_DISPLAY_PORT then variable ret is uninitialized and this is
checked for > 0 at the end of the function. Ret should be initialized,
I believe setting it to zero is a correct default.

It works fine and was only disabled because primary GPUs
don't enter runpm if there is a console bound to the fbdev due
to the kmap. This will at least allow runpm on secondary cards.

Making them an error confuses users and the errors are harmless

This reverts commit 134f98bcf1b898fb9d6f2b91bc85dd2e5478b4b8.
The r8153_mac_clk_spd() is used for RTL8153A only, because the register
table of RTL8153B is different from RTL8153A. However, this function would
be called when RTL8153B calls r8153_first_init() and r8153_enter_oob().
That causes RTL8153B becomes unstable when suspending and resuming. The
worst case may let the device stop working.
Besides, revert this commit to disable MAC clock speed down for RTL8153A.
It would avoid the known issue when enabling U1. The data of the first
control transfer may be wrong when exiting U1.

warning in iwl_pcie_rx_handle())
We can't call netif_napi_add() with rxq-lock held, as there is a potential
for deadlock as spotted by lockdep (see below). rxq->lock is not
protecting anything over the netif_napi_add() codepath anyway, so let's
drop it just before calling into NAPI.

The hdcp_i2c_offsets[] array did not have an entry for
HDCP_MESSAGE_ID_WRITE_CONTENT_STREAM_TYPE so it led to an off by one
read overflow. I added an entry and copied the 0x0 value for the offset
from similar code in drivers/gpu/drm/amd/display/modules/hdcp/hdcp_ddc.c.
I also declared several of these arrays as having HDCP_MESSAGE_ID_MAX
entries. This doesn't change the code, but it's just a belt and
suspenders approach to try future proof the code.

The copy_to_user() function returns the number of bytes remaining but
we want to return -EFAULT to the user if it can't complete the copy.
The "st" variable only holds zero on success or negative error codes on
failure so the type should be int.

We know which WM0 (normal vs. SAGV) we supposedly programmed
into the hardware, so just check against that instead of accepting

Seems to me that if we calculate WM0 using the bumped up SAGV latency
we need to calculate the transition watermark accordingly. Track it
alongside the other watermarks.

When we switch between SAGV on vs. off we need to reprogram all
plane wateramrks accordingly. Currently skl_wm_add_affected_planes()
totally ignores the SAGV watermark and just assumes we will use
the normal WM0.
Fix this by utilizing skl_plane_wm_level() which picks the
correct watermark based on use_sagv_wm. Thus we will force
an update on all the planes whose watermark registers need
to be reprogrammed.

Populate conn_state->max_bpc with something sensible from the start.
Otherwise it's possible that we get to compute_sink_pipe_bpp() with
max_bpc==0.
The specific scenario goes as follows:
1. Initial connector state allocated with max_bpc==0
2. Trigger a modeset on the crtc feeding the connector, without
actually adding the connector to the commit
3. drm_atomic_connector_check() is skipped because the
connector has not yet been added, hence conn_state->max_bpc
retains its current value
4. drm_atomic_helper_check_modeset() ->
drm_atomic_add_affected_connectors() -> the connector
is now part of the commit
5. compute_baseline_pipe_bpp() -> MISSING_CASE(max_bpc==0)
Note that pipe_bpp itself may not be populated on pre-g4x machines,
in which case we just fall back to max_bpc==8 and let .compute_config()
limit the resulting pipe_bpp further if necessary.

While reviewing patches for handling workarounds related to gen9 bc, Imre
from Intel discovered that we're using spt_hpd_irq_setup() on ICP+ PCHs
despite it being almost the same as icp_hpd_irq_setup(). Since we need to
be calling icp_hpd_irq_setup() to ensure that CML-S/TGP platforms function
correctly anyway, let's move platforms using PCH_ICP which aren't handled
by gen11_hpd_irq_setup() over to icp_hpd_irq_setup().

For Legacy S3 suspend/resume GEN9 BC needs to enable and
setup TGP PCH.
v2:
* Move Wa_14010685332 into it's own function - vsyrjala
* Add TODO comment about figuring out if we can move this workaround - imre
v3:
* Rename cnp_irq_post_reset() to cnp_display_clock_wa()
* Add TODO item mentioning we need to clarify which platforms this
workaround applies to
* Just use ibx_irq_reset() in gen8_irq_reset(). This code should be
functionally equivalent on gen9 bc to the code v2 added
* Drop icp_hpd_irq_setup() call in spt_hpd_irq_setup(), this looks to be
more or less identical to spt_hpd_irq_setup() minus additionally enabling
one port. Will update i915 to use icp_hpd_irq_setup() for ICP in a
separate patch.
v4:
* Revert Wa_14010685332 system list in comments to how it was before
* Add back HAS_PCH_SPLIT() check before calling ibx_irq_reset()
