"Here is the large set of staging driver changes for 6.2-rc1.
Another round of cleanups for staging drivers with no big additions.
Overall more lines were removed than added, always a nice sign, with
nothing happening in here other than general coding style cleanups and
minor fixes in the drivers. Full, boring, details are in the shortlog.
All of these have been in linux-next for a while with no reported
problems"

Support the kernel's nomodeset parameter for all PCI-based fbdev
drivers that use aperture helpers to remove other, hardware-agnostic
graphics drivers.
The parameter is a simple way of using the firmware-provided scanout
buffer if the hardware's native driver is broken. The same effect
could be achieved with per-driver options, but the importance of the
graphics output for many users makes a single, unified approach
worthwhile.
With nomodeset specified, the fbdev driver module will not load. This
unifies behavior with similar DRM drivers. In DRM helpers, modules
first check the nomodeset parameter before registering the PCI
driver. As fbdev has no such module helpers, we have to modify each
driver individually.
The name 'nomodeset' is slightly misleading, but has been chosen for
historical reasons. Several drivers implemented it before it became a
general option for DRM. So keeping the existing name was preferred over
introducing a new one.
v2:
* print a warning if a driver does not init (Helge)
* wrap video_firmware_drivers_only() in helper

"Here is the large set of staging driver changes for 6.1-rc1.
Nothing really interesting in here at all except we deleted a driver
(fwserial) as no one had been using it for a long time. Other than
that, just the normal cleanups and minor fixes:
- rtl8723bs driver cleanups
- loads of r8188eu driver cleanups, making the driver smaller and
fixing up some firmware dependency issues.
- vt6655 driver cleanups.
- lots of other small staging driver cleanups.

If ioremap_wc() fails, the code jumps to the "exit" label and forgets to
free the bus memory mapped into "sm750_dev->pvReg". Mapped bus memory must
always be freed by calling iounmap().
Call iounmap(sm750_dev->pvReg) when the above-mentioned failures happen.
The site of the missing iounmap() has been detected by Smatch.

strlcpy is marked as deprecated in Documentation/process/deprecated.rst,
and there is no functional difference when the caller expects truncation
(when not checking the return value). strscpy is relatively better as it
also avoids scanning the whole source string.
This silences the related checkpatch warnings from:

Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.
Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions, as through
the generic framework PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

The kbuild documentation clearly shows that the documents
there are written at different times: some use markdown,
some use their own peculiar logic to split sections.
Convert everything to ReST without affecting too much
the author's style and avoiding adding uneeded markups.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
