- the documented vendor prefix for Renesas is "renesas,"

Commit 723de0f917 ("staging: most: remove device from interface
structure") moved registration of driver-provided struct device to
the most subsystem. This updated dim2 driver as well.
However, struct device passed to register_device() becomes refcounted,
and must not be explicitly deallocated, but must provide release method
instead. Which is incompatible with managing it via devres.
This patch makes the device structure allocated without devres, adds
device release method, and moves device destruction there.

Commit 723de0f917 ("staging: most: remove device from interface
structure") moved registration of driver-provided struct device to
the most subsystem.
Dim2 used to register the same struct device to provide a custom device
attribute. This causes double-registration of the same struct device.
Fix that by moving the custom attribute to driver's dev_groups.
This moves attribute to the platform_device object, which is a better
location for platform-specific attributes anyway.

Here is the large set of Staging and IIO driver patches for 5.9-rc1.
Lots of churn here, but overall the size increase in lines added is
small, while adding a load of new IIO drivers.
Major things in here:
- lots and lots of IIO new drivers and frameworks added
- IIO driver fixes and updates
- lots of tiny coding style cleanups for staging drivers
- vc04_services major reworks and cleanups
We had 3 set of drivers move out of staging in this round as well:
- wilc1000 wireless driver moved out of staging
- speakup moved out of staging
- most USB driver moved out of staging
Full details are in the shortlog.
All of these have been in linux-next with no reported issues. The last
few changes here were to resolve reported linux-next issues, and they
seem to have resolved the problems.

Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over

decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:

This patch removes the expression that makes use of a priori knowledge
about channel numbers to calculate an array index.
The expression 'peer = 1 - channel' utilizes the fact that an USB interface
that operates on the asynchronous data of the Network only has two
endpoints. Hence, channel being 0 or 1. The replacement is more simple and
less confusing when reading the code.
