From commit 73dec95e6b ("drm/i915: Emit to ringbuffer directly"),
copy_gma_to_hva() now returns copied data length instead of 0, so
need to change error return check for that.
Note: Looks this is caused by backmerge conflict resolving, so
4.11-rc4 is not impacted as commit 73dec95e6b ("drm/i915: Emit to

Several major vendor USB-C->HDMI converters, in particular the DA200,
fail to recover a 5.4 GHz 1 lane signal if the link N is greater than
0x80000.
The link M and N depend on the pixel clock and link clock ratio. With
current code link N exceeds 0x80000 only when link clock >= 540000
kHz. Except for the eDP intermediate link clocks, at least the four
least significant bits are always zero. Just one bit shift right would
be enough to bring even the DP 1.4 810000 kHz link clock under 0x80000
link N. The pixel clock for modes that require a link clock >= 540000
kHz would also have several least significant bits zero. Unless the user
provides a mode with an odd pixel clock value, we can reduce the numbers
to reach the goal, with no loss in precision.
The DP spec even mentions sources making choices that "allow for static
and relatively small Mvid and Nvid values", thus reducing the link M/N
regardless of the sink in question seems justified.
Everything here is based on the work and information gathered by Clint
Taylor <clinton.a.taylor@intel.com>. This is just an iteration to reduce
the parameters regardless of lane count, link rate, or sink.

Geminilake platform sports a native HDMI 2.0 controller, and is
capable of driving pixel-clocks upto 594Mhz. HDMI 2.0 spec
mendates scrambling for these higher clocks, for reduced RF footprint.
This patch checks if the monitor supports scrambling, and if required,
enables it during the modeset.
V2: Addressed review comments from Ville:
- Do not track scrambling status in DRM layer, track somewhere in
driver like in intel_crtc_state.
- Don't talk to monitor at such a low layer, set monitor scrambling
in intel_enable_ddi() before enabling the port.
V3: Addressed review comments from Jani
- In comments, function names, use "sink" instead of "monitor",
so that the implementation could be close to the language of
HDMI spec.
V4: Addressed review comment from Maarten
- scrambling -> hdmi_scrambling
- high_tmds_clock_ratio -> hdmi_high_tmds_clock_ratio
V5: Addressed review comments from Ville and Ander
- Do not modifiy the crtc_state after compute_config. Move all
scrambling and tmds_clock_ratio calcutations to compute_config.
- While setting scrambling for source/sink, do not check the
conditions again, just go by the crtc_state flags. This will
simplyfy the condition checks.
V6: Addressed review comments from Ville
- Do not add IS_GLK check in disable/enable function, instead add it
in compute_config, while setting state flags.
- Remove unnecessary paranthesis.
- Simplyfy handle_sink_scrambling function as suggested.
- Add readout code for scrambling status in get_ddi_config and add a
check for the same in pipe_config_compare.
V7: Addressed review comments from Ander/Ville
- No separate function for source scrambling, make it inline
- Align the last line of the macro TRANS_DDI_HDMI_SCRAMBLING_MASK
- Do not add platform check while setting source scrambling
- Use pipe_config instead of crtc->config to set sink scrambling
- To readout scrambling status, Compare with SCRAMBLING_MASK
not any of its bits
- Remove platform check in intel_pipe_config_compare while checking
scrambling status
V8: Fixed mege conflict, Addressed review comments from Ander
- Remove the desciption/comment about scrambling fom the caller, move
it to the function
- Move the IS_GLK check into scrambling function
- Fix alignment
V9: Fixed review comments from Ville, Ander
- Pass the scrambling state variables as bool input to the sink_scrambling

If the request->wa_tail is 0 (because it landed exactly on the end of
the ringbuffer), when we reconstruct request->tail following a reset we
fill in an illegal value (-8 or 0x001ffff8). As a result, RING_HEAD is
never able to catch up with RING_TAIL and the GPU spins endlessly. If
the ring contains a couple of breadcrumbs, even our hangcheck is unable
to catch the busy-looping as the ACTHD and seqno continually advance.

When the rdma device is removed, we must cleanup all
the rdma resources within the DEVICE_REMOVAL event
handler to let the device teardown gracefully. When
this happens with live I/O, some memory regions are
occupied. Thus, track them too and dereg all the mr's.
We are safe with mr access by iscsi_iser_cleanup_task.
