This set also includes quite a number of bug fixes of particularly
remove functions.

Necessary due to issue pointed out in Bart Van Assche's patch:
docs/driver-model: Document device.groups

V2: Rebase due to patch reordering.
V3: Pull various error fixes and cleanups out into their own patches.

This costs us nothing in event storage (as we are carrying a 64 bit
timestamp in the structure) and gives us lots more room to play with.

Also allows for more channels which some parts need.

V2: Cleanup some loose ends (such as the switch with only one option now).

This is as light as possible on changes to current drivers.
Some drivers make assumptions that their masks fit in a single
long.  Given they were previously working this is clearly valid if
not tidy.

The max1363 is an example where there should be no such assumptions.

V2: Add the new ad5933

The scan mask will be dynamically assigned in register, so don't
use it before that.

In adis16260 I've moved it as I know this driver has userspace code.
Same for sca3000 where it is cost free due to hardware buffer.
Can do that for the others, but in theory userspace code should always
have been checking these and setting them appropriately anyway!

V2: Clear default mask out of adis16400 as reported by Michael

Change suggested by Arnd Bergmann.

No real reason to have two chrdevs per device. This step merges them into one.
Currently this means that events will only work on devices with buffers. THat will
be remedied shortly.

V2: set name for event attribute groups.  Otherwise they all sorts of fun occurs on
dynamic channel event attribute creation.

netif_notify_peers() caused a kernel warning in netvsc_linkstatus_callback(),
because netvsc_linkstatus_callback() is within IRQ context. So we move

zero delay.

kernels 2.6.32 and later.
