Factor out a function setting the encoder and CRTC in the connector
atomic state, required by a follow up patch.

Split calling the CRTC/encoder disabling hooks and updating the CRTC and
DPLL object states from updating the CRTC and atomic state and other
global state (BW, CDCLK, DBUF) into separate functions. When disabling a
bigjoiner configuration the latter step can be done only after all the
linked pipes are disabled, so this change prepares for that.
No functional changes.

During HW state readout/sanitization an up-to-date connector atomic
state will be required by a follow-up patch, which can disable CRTCs
with an encoder (and calling the correct encoder hooks happens via the
connector atomic state encoder pointer). So update the connector state
already before the CRTC sanitize/disable step. For now this doesn't make
a difference, since intel_modeset_update_connector_atomic_state() will
update/enable the atomic state only for connectors that have an enabled
encoder/CRTC. Such CRTCs/encoders will not be affected by
intel_sanitize_crtc().
v2: Add comment about why the connector state needs to be up-to-date.

Make sure that the CRTC state is reset correctly, as expected after
disabling the CRTC.
In particular this change will:
- Zero all the CSC blob pointers after intel_crtc_free_hw_state()
has freed them.
- Zero the shared DPLL and port PLL pointers and clear the
corresponding CRTC reference flag in the PLL state.
- Reset all the transcoder and pipe fields.
v2:
- Reset fully the CRTC state. (Ville)
- Clear pipe active flags in the DPLL state.
v3:
- Clear only the CRTC reference flag and add a helper for this.
(Ville)
v4:
- Rebased on previous patch, adding
intel_unreference_shared_dpll_crtc() separately. (Ville)

Add helpers to reference/unreference a shared DPLL tracking the use of
it by a given CRTC.
This prepares for the next patch, which unreferences a DPLL during CRTC

For a bigjoiner configuration display->crtc_disable() will be called
first for the slave CRTCs and then for the master CRTC. However slave
CRTCs will be actually disabled only after the master CRTC is disabled
(from the encoder disable hooks called with the master CRTC state).
Hence the slave PIPEDMCs can be disabled only after the master CRTC is
disabled, make this so.
intel_encoders_post_pll_disable() must be called only for the master
CRTC, as for the other two encoder disable hooks. While at it fix this
up as well. This didn't cause a problem, since
intel_encoders_post_pll_disable() will call the corresponding hook only
for an encoder/connector connected to the given CRTC, however slave
CRTCs will have no associated encoder/connector.

There is no need to exclusively set the .owner member of the struct
device_driver when defining the platform_driver struct. The Linux core

Since topology state is being added to drm_atomic_state now all
drm_modeset_lock required are being taken from core. This raises
an issue when we try to loop over connector and assign vcpi id to
our streams as we did not have atomic state to derive acquire_ctx
from. We fill in stream info if dpmst encoder is found before
enabling hdcp. intel_hdcp_required_stream will be broken which
will only set the content type.

before assigning it to the RGB coefficients, which is causing the IGT
pixel-format tests to fail. So, use the drm_fixp2int_round() fixed-point

Consider a configuration like this:
1, efifb (or simpledrm) is built-in;
2, a native display driver (such as radeon) is also built-in.
As Javier said, this is not a common configuration (the native display
driver is usually built as a module), but it can happen and cause some
trouble.
In this case, since efifb, radeon and sysfb are all in device_initcall()
level, the order in practise is like this:
efifb registered at first, but no "efi-framebuffer" device yet. radeon
registered later, and /dev/fb0 created. sysfb_init() comes at last, it
registers "efi-framebuffer" and then causes an error message "efifb: a
framebuffer is already registered". Make sysfb_init() to be subsys_
initcall_sync() can avoid this. And Javier Martinez Canillas is trying
to make a more general solution in commit 873eb3b11860 ("fbdev: Disable
sysfb device registration when removing conflicting FBs").
However, this patch still makes sense because it can make the screen
display as early as possible (We cannot move to subsys_initcall, since
sysfb_init() should be executed after PCI enumeration).

In no journal mode, ext4_finish_convert_inline_dir() can self-deadlock
by calling ext4_handle_dirty_dirblock() when it already has taken the
directory lock. There is a similar self-deadlock in
ext4_incvert_inline_data_nolock() for data files which we'll fix at
the same time.
A simple reproducer demonstrating the problem:
mke2fs -Fq -t ext2 -O inline_data -b 4k /dev/vdc 64
mount -t ext4 -o dirsync /dev/vdc /vdc
cd /vdc
mkdir file0
cd file0
touch file0
touch file1
attr -s BurnSpaceInEA -V abcde .
touch supercalifragilisticexpialidocious

If there are failures while changing the mount options in
__ext4_remount(), we need to restore the old mount options.
This commit fixes two problem. The first is there is a chance that we
will free the old quota file names before a potential failure leading
to a use-after-free. The second problem addressed in this commit is
if there is a failed read/write to read-only transition, if the quota
has already been suspended, we need to renable quota handling.

The ext4_dirhash() will *almost* never fail, especially when the hash
tree feature was first introduced. However, with the addition of
support of encrypted, casefolded file names, that function can most
certainly fail today.
So make sure the callers of ext4_dirhash() properly check for
failures, and reflect the errors back up to their callers.
