e499cd3102 Merge tag 'spi-remove-void' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi 
Mark Brown says:

====================
spi: Make remove() return void

This series from Uwe Kleine-König converts the spi remove function to
return void since there is nothing useful that we can do with a failure
and it as more buses are converted it'll enable further work on the
driver core.

a0386bba70 spi: make remove callback a void function 
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

6df4432a5e drm/panel: simple: Assign data from panel_dpi_probe() correctly 
In the function panel_simple_probe() the pointer panel->desc is
assigned to the passed pointer desc. If function panel_dpi_probe()
is called panel->desc will be updated, but further on only desc
will be evaluated. So update the desc pointer to be able to use
the data from the function panel_dpi_probe().

When possible use dev_err_probe help to properly deal with the
PROBE_DEFER error, the benefit is that DEFER issue will be logged
in the devices_deferred debugfs file.
And using dev_err_probe() can reduce code size, and the error value
gets printed.

9bf7123bb0 drm/panel: Delete panel on mipi_dsi_attach() failure 
Many DSI panel drivers fail to clean up their panel references on
mipi_dsi_attach() failure, so we're leaving a dangling drm_panel
reference to freed memory. Clean that up on failure.

Noticed by inspection, after seeing similar problems on other drivers.
Therefore, I'm not marking Fixes/stable.

If we fail to attach (e.g., because 1 of 2 dual-DSI controllers aren't

This problem exists since the driver's introduction, but is especially

1a84a308ac drm/panel-simple: Add Vivax TPC-9150 panel v6 
The model and make of the LCD panel of the Vivax TPC-9150 is unknown,
hence the panel settings that were retrieved with a FEX dump are named
after the device NOT the actual panel.

The LCD in question is a 50 pin MISO TFT LCD panel of the resolution
1024x600 used by the aforementioned device.

Version 2, as Thierry kindly suggested that I fix the order in which the
panel was ordered compared to others.

Version 3, filling in the required info suggested by Sam. Plus some
factual issues that I've corrected myself (tested working)

Version 4, rearranged the display parameters and fix invalid bit format
issue. (Thanks Sam)

Version 5, referred to FEX file instead of manual debugging for
information.

Version 6, same as above. This time, it'll be documented.

A bit of context first: I experimented with this a long time ago whilst
I was first learning how to get Linux running on Allwinner boards, I
didn't have many resources at hand so this was quite slow. Anyways, I
stumbled upon this guide (https://linux-sunxi.org/LCD) and was reading
about how to setup the LCD for my tablet. Since I was able to make a
proper FEX dump, I was also able to read the correct parameters for
myself without relying on leaked documents or part numbers and whatnot.

In the FEX dump the value lcd_frm IS SET to 1, which means, at least
according to the document, that this display is INDEED an 18 bit per
pixel panel. Compiling U-Boot and seeing the tux in proper colors
confirmed this. As per Sam Ravnborg's suggestion, I've changed the panel
to his format "MEDIA_BUS_FMT_RGB666_1X7X3_SPWG", however this does not
lead to any actual change in regards to the functionality since the sunxi
panel driver just ignores this value. However, hopefully this clears up
any errors down the road as either the driver becomes advanced enough to
not ignore this value or that some other piece of software relies on
this value being known. PS: Apologies to the maintainers that have to
endure my misjudgement about how these things work.

As for the concerns about a single patch series, I wasn't sure where to
send the patches as they clearly aren't dt-bindings related and my
previous patches have ended up in drm-misc-fixes anyway. So I'm guessing
I'll be fine if I just post them in the list from last time???
