cf33de1799 drm/bridge: ti-sn65dsi86: Config number of DP lanes Mo' Betta 
The driver used to say that the value to program into bridge register
0x93 was dp_lanes - 1.  Looking at the datasheet for the bridge, this
is wrong.  The data sheet says:
* 1 = 1 lane
* 2 = 2 lanes
* 3 = 4 lanes

A more proper way to express this encoding is min(dp_lanes, 3).

At the moment this change has zero effect because we've hardcoded the
number of DP lanes to 4.  ...and (4 - 1) == min(4, 3).  How fortunate!
...but soon we'll stop hardcoding the number of lanes.

fa8a66c687 drm/bridge: ti-sn65dsi86: Don't use MIPI variables for DP link 
The ti-sn65dsi86 is a bridge from MIPI to DP and thus has two links:
the MIPI link and the DP link.  The two links do not need to have the
same format or number of lanes.  Stop using MIPI variables when
talking about the DP link.

This has zero functional change because:
* currently we are hardcoding the MIPI link as unpacked RGB888 which
  requires 24 bits and currently we are not changing the DP link rate
  from the bridge's default of 8 bits per pixel.
* currently we are hardcoding both the MIPI and DP as being 4 lanes.

This is all in prep for fixing some of the above.

2f8fcc7794 drm/bridge: ti-sn65dsi86: zero is never greater than an unsigned int 
When we iterate over ti_sn_bridge_dp_rate_lut, there's no reason to
start at index 0 which always contains the value 0.  0 is not a valid
link rate.

This change should have no real effect but is a small cleanup.

These two things were in one function.  Split into two.  This looks

e62bf83aa1 drm/irq: remove check on dev->dev_private 
There is no real reason to require drivers to set and use
dev->dev_private. Indeed, the current recommendation, as documented in
drm_device.h, is to embed struct drm_device in the per-device struct
instead of using dev_private.

Remove the requirement for dev_private to have been set to indicate
driver initialization.

For background, quoting Daniel Vetter:

Now there might be some hilarious races this papers over, but:

- Proper drivers should only call drm_dev_register once everything is
  set up, including this stuff here. No race possible with anything else
  really.

- Slightly more wobbly drivers, including the legacy ones, all use
  drm_global_mutex. This was the former BKL, which means that it was
  impossible for soeone to go through the load/unload/reload (between
  lastclose and firstopen) paths and also run the ioctl. But the ioctl
  had to be made unlocked because blocking there killed X:

	 commit 8f4ff2b06a
	 Author: Ilija Hadzic <ihadzic@research.bell-labs.com>
	 Date:   Mon Oct 31 17:46:18 2011 -0400

	     drm: do not sleep on vblank while holding a mutex

  The even more legacy DRM_CONTROL ioctl stayed fully locked. But the
  file open/close paths are still fully locked, and that's the only
  place legacy drivers should call drm_irq_install/uninstall, so should
  all still be fully ordered and protected and happy.

4017ad7bbc drm: Nerf drm_global_mutex BKL for good drivers 
This catches the majority of drivers (unfortunately not if we take
users into account, because all the big drivers have at least a
lastclose hook).

With the prep patches out of the way all drm state is fully protected
and either prevents or can deal with the races from dropping the BKL
around open/close. The only thing left to audit are the various driver
hooks - by keeping the BKL around if any of them are set we have a
very simple cop-out!

Note that one of the biggest prep pieces to get here was making
dev->open_count atomic, which was done in

591a2abf14 drm: Push drm_global_mutex locking in drm_open 
We want to only take the BKL on crap drivers, but to know whether
we have a crap driver we first need to look it up. Split this shuffle
out from the main BKL-disabling patch, for more clarity. Historical
aside: When the kernel-wide BKL was removed, it was replaced by
drm_global_mutex within the scope of the drm subsystem hence why these
two things are (almost) interchangeable as concepts here.

Since the minors are refcounted drm_minor_acquire is purely internal
and this does not have a driver visible effect.

v2: Push the locking even further into drm_open(), suggested by Chris.
This gives us more symmetry with drm_release(), and maybe a futuer
avenue where we make drm_global_mutex locking (partially) opt-in like
with drm_release_noglobal().

v3:
- Actually push this stuff correctly, don't unlock twice (Chris)
- Fix typo on commit message, plus explain why BKL = drm_global_mutex

64914da24e drm/fbdev-helper: don't force restores 
Instead check for master status, in case we've raced.

This is the last exception to the general rule that we restore fbcon
only when there's no master active. Compositors are supposed to drop
their master status before they switch to a different console back to
text mode (or just switch to text mode directly, without a vt switch).

This is known to break some subtests of kms_fbcon_fbt in igt, but they're
just wrong - it does a graphics/text mode switch for the vt without
updating the master status.

Also add a comment to the drm_client->restore hook that this is expected
going forward from all clients (there's currently just one).

v2: Also drop the force in pan_display

v3: Restore the _force to pan_display, this actually means _locked in that
path. Spotted by Noralf.
