Deterministic algorithm:

If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:

If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

The FRD350H54004 panel was marked as having active-high VSYNC and HSYNC
signals, which sorts-of worked, but resulted in the picture fading out
under certain circumstances.
Fix this issue by marking VSYNC and HSYNC signals active-low.

Gives us proper nonblocking support for free, and a pile of other
things. The tilcdc code is simply old enough that it was never
converted over, but was stuck forever with the copypasta from when it
was initially merged.
The riskiest thing with this conversion is maybe that there's an issue
with the vblank handling or vblank event handling, which will upset
the modern commit support in atomic helpers. But from a cursory review
drm_crtc_vblank_on/off is called in the right places, and the event
handling also seems to exist (albeit with much hand-rolling and
probably some races, could perhaps be converted over to
drm_crtc_arm_vblank_event without any real loss).
Motivated by me not having to hand-roll the dma-fence annotations for
this.
v2: Clear out crtc_state->event when we're handling the event, to
avoid upsetting the helpers (reported by Jyri).
v3: Also send out even whent the crtc is getting disabled. Tilcdc looks a
bit like conversion to simple display helpers would work out really
nice.

Of the DPMS code, only ON and OFF states are used. Simplify mode setting
by moving both into separate functions and removing the rest.
The original code busy waited in the middle of updating the screen state
in SEQ1. To simplify the procedure, the new code busy waits first and then
updates SEQ1 in one chunk.
The DPMS code also set the LUT before enabling the screen. The patch moves
this code into the simple-display pipe's enable function.

The simple pipe's disable function disables the screen by calling
mgag200_disable_screen(). The simple pipe's enable function enables the
screen by calling mgag200_enable_display().
During modeset operations the screen is off and remains off. It's only
enabled after the modeset has been completed. Therefore remove all code
that sets or clears the <scroff> field while in modeset.
The related code also modifies the <syncrst> field in SEQ0. For now, keep
this code in place.

The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function
returns the number of the created entries in the DMA address space.
However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and
dma_unmap_sg must be called with the original number of the entries
passed to the dma_map_sg().
struct sg_table is a common structure used for describing a non-contiguous
memory buffer, used commonly in the DRM and graphics subsystems. It
consists of a scatterlist with memory pages and DMA addresses (sgl entry),
as well as the number of scatterlist entries: CPU pages (orig_nents entry)
and DMA mapped pages (nents entry).
It turned out that it was a common mistake to misuse nents and orig_nents
entries, calling DMA-mapping functions with a wrong number of entries or
ignoring the number of mapped entries returned by the dma_map_sg()
function.
To avoid such issues, lets use a common dma-mapping wrappers operating
directly on the struct sg_table objects and use scatterlist page
iterators where possible. This, almost always, hides references to the
nents and orig_nents entries, making the code robust, easier to follow
and copy/paste safe.

It doesn't hurt to add the bridge in the global bridge list also for
platform specific dw-hdmi drivers which are based on the component
framework. This can be achieved by moving the drm_bridge_add() function
call from dw_hdmi_probe() to __dw_hdmi_probe(). A counterpart movement
for drm_bridge_remove() is also needed then. Moreover, since drm_bridge_add()
initializes &bridge->hpd_mutex, this may help those platform specific
dw-hdmi drivers(based on the component framework) avoid accessing the
uninitialized mutex in drm_bridge_hpd_notify() which is called in
dw_hdmi_irq(). Putting drm_bridge_add() in __dw_hdmi_probe() just before
it returns successfully should bring no logic change for platforms based
on the DRM bridge API, which is a good choice from safety point of view.
Also, __dw_hdmi_probe() is renamed to dw_hdmi_probe() since dw_hdmi_probe()
does nothing else but calling __dw_hdmi_probe(). Similar renaming applies
to the __dw_hdmi_remove()/dw_hdmi_remove() pair.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

If smtcfb_pci_probe() does not detect a valid chip it cleans up
everything and returns 0. This can result in various bad things later.
The patch sets the error code on the corresponding path.

fb_probe() can successfully allocate a new frame buffer, but then fail
to perform some operations with regulator. In these cases fb_probe()
goes to label err_pm_runtime_disable where the frame buffer is not
released. The patch makes fb_probe() to go to label err_release_fb on
corresponding error handling paths.

The drm/omap driver was fixed to correct an issue where using a
divider of 32 breaks the DSS despite the TRM stating 32 is a valid
number. Through experimentation, it appears that 31 works, and
it is consistent with the value used by the drm/omap driver.
This patch fixes the divider for fbdev driver instead of the drm.

On calling pm_runtime_get_sync() the reference count of the device
is incremented. In case of failure, decrement the
reference count before returning the error.

neofb_probe() calls neo_scan_monitor() that can successfully allocate a
memory for info->monspecs.modedb and proceed to case 0x03. There it does
not free the memory and returns -1. neofb_probe() goes to label
err_scan_monitor, thus, it does not free this memory through calling
fb_destroy_modedb() as well. We can not go to label err_init_hw since
neo_scan_monitor() can fail during memory allocation. So, the patch frees
the memory directly for case 0x03.

savagefb_probe() calls savage_init_fb_info() that can successfully
allocate memory for info->pixmap.addr but then fail when
fb_alloc_cmap() fails. savagefb_probe() goes to label failed_init and
does not free allocated memory. It is not valid to go to label
failed_mmio since savage_init_fb_info() can fail during memory
allocation as well. So, the patch free allocated memory on the error
handling path in savage_init_fb_info() itself.

and scr_memsetw(). These sorts of multiplication factors need to be wrapped
in array3_size().

Since we lack the hardware (or proper emulator setup) for
testing needed changes add FIXMEs to document the issues
(so at least they are not forgotten).

Add FIXME about using the C code variants (APUS ones) in the future.
