[ Upstream commit 48bfd02569f5db49cc033f259e66d57aa6efc9a3 ]

If it is async, runqueue_node is freed in g2d_runqueue_worker on another
worker thread. So in extreme cases, if g2d_runqueue_worker runs first, and
then executes the following if statement, there will be use-after-free.

[ Upstream commit 4a059559809fd1ddbf16f847c4d2237309c08edf ]

Fix a wrong error return by dropping an error return.

When vidi driver is remvoed, if ctx-&gt;raw_edid isn't same as fake_edid_info
then only what we have to is to free ctx-&gt;raw_edid so that driver removing
can work correctly - it's not an error case.

[ Upstream commit 2ef0785b30bd6549ddbc124979f1b6596e065ae2 ]

The empty stub functions are defined as global functions, which
causes a warning because of missing prototypes:

drivers/gpu/drm/exynos/exynos_drm_g2d.h:37:5: error: no previous prototype for 'g2d_open'
drivers/gpu/drm/exynos/exynos_drm_g2d.h:42:5: error: no previous prototype for 'g2d_close'

Mark them as 'static inline' to avoid the warning and to make
them behave as intended.

[ Upstream commit 996e1defca34485dd2bd70b173f069aab5f21a65 ]

HFP/HBP/HSA/EOT_PACKET modes in Exynos DSI host specifies
0 = Enable and 1 = Disable.

The logic for checking these mode flags was correct before
the MIPI_DSI*_NO_* mode flag conversion.

This patch is trying to fix this MIPI_DSI*_NO_* mode flags handling
Exynos DSI host and update the mode_flags in relevant panel drivers.

Pull iommu updates from Joerg Roedel:

 - remove the bus_set_iommu() interface which became unnecesary because
   of IOMMU per-device probing

 - make the dma-iommu.h header private

 - Intel VT-d changes from Lu Baolu:
	  - Decouple PASID and PRI from SVA
	  - Add ESRTPS &amp; ESIRTPS capability check
	  - Cleanups

 - Apple DART support for the M1 Pro/MAX SOCs

 - support for AMD IOMMUv2 page-tables for the DMA-API layer.

   The v2 page-tables are compatible with the x86 CPU page-tables. Using
   them for DMA-API prepares support for hardware-assisted IOMMU
   virtualization

 - support for MT6795 Helio X10 M4Us in the Mediatek IOMMU driver

 - some smaller fixes and cleanups

<title>drm/exynos: Fix return type for mixer_mode_valid and hdmi_mode_valid</title>

<id>urn:sha1:1261255531088208daeca818e2b486030b5339e5</id>
<content type='text'>
The field mode_valid in exynos_drm_crtc_ops is expected to be of type enum
drm_mode_status (*mode_valid)(struct exynos_drm_crtc *crtc,
                                   const struct drm_display_mode *mode);

Likewise for mode_valid in drm_connector_helper_funcs.

The mismatched return type breaks forward edge kCFI since the underlying
function definition does not match the function hook definition.

The return type of mixer_mode_valid and hdmi_mode_valid should be changed
from int to enum drm_mode_status.

<title>drm/exynos: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi</title>

<id>urn:sha1:372a2eaf9bed96395699eb4c2d32e3fe48830e8c</id>
<content type='text'>
Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi.

This driver calls drm_detect_hdmi_monitor() to receive the same
information, which is less efficient.

Avoid calling drm_detect_hdmi_monitor() and use drm_display_info.is_hdmi
instead.

Pull sound updates from Takashi Iwai:
 "As the diffstat shows, we've had lots of developments in a wide range
  at this time; the majority of changes are about ASoC, including
  subsystem-wide cleanups, continued SOF / Intel updates and a bunch of
  new drivers (as usual), while there have been some significant (but
  almost invisible) improvements in ALSA core side, too.

  Below are some highlights:

  Core:

   - Faster lookups of control elements with Xarray; normal user won't
     notice, but on the devices with tons of control elements, it can be
     visibly faster

   - Support for input validation for controls; this will harden for
     badly written drivers in general with a slight overhead

   - Deferred async signal handling for working around the potential
     deadlocks

   - Cleanup / refactoring raw MIDI locking code

  ASoC:

   - Restructing of the set_fmt() callbacks for making things clearer in
     situations like CODEC to CODEC links

   - Clean up and modernizing the DAI naming scheme setups

   - Merge of more of the Intel AVS driver stack, including some board
     integrations

   - New version 4 mechanism for communication with SOF DSPs

   - Suppoort for dynamically selecting the PLL to use at runtime on
     i.MX platforms

   - Improvements for CODEC to CODEC support in the generic cards

   - Support for AMD Jadeite and various machines, AMD RPL, Intel
     MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra
     MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and
     WAS883x, and Texas Instruments TAS2780

  HD- and USB-audio:

   - Continued improvement for CS35L41 (sub)codec support

   - More quirks for various devices (HP, Lenovo, Dell, Clevo)"
