With my job change kernel work will be "own time"; I'm keeping lguest
and modules (and the virtio standards work), but virtio kernel has to
go.
This makes it clear that Michael is in charge. He's good, but having
me watch over his shoulder won't help.
Good luck Michael!

The patch adds a debug driver, which dumps the power states
of all the North complex (NC) devices. This debug interface is
useful to figure out the NC IPs which blocks the S0ix
transitions on the platform. This is extremely useful during
enabling PM on customer platforms and derivatives.
This

Based on review comments
- Changed to tristate instead of bool
- Moved config to kconfig.debug
- Added debug in module name
- Returning -ENXIO on debugfs file create error

Commit 13060b64b819 ("vfio: Add and use device request op for vfio
bus drivers") incorrectly makes use of an interruptible timeout.
When interrupted, the signal remains pending resulting in subsequent
timeouts occurring instantly. This makes the loop spin at a much
higher rate than intended.

Bah. I forgot to add [RFC] to the subject. This patch isn't yet ready
for submission, I just wanted to get some initial feedback on it.
thanks

Hi, I know this patch is
It was noted that the 32bit implementation of ktime_divns
was doing unsgined division adn didn't properly handle
negative values.
This patch fixes the problem by checking and preserving
the sign bit, and then reapplying it if appropriate
after the division.
Unfortunately there is some
Added support to calculate lux value from visible
and IR spectrum adc count values. Also added IIO_LIGHT
channel to enable user read the lux value directly
from device using illuminance input ABI.

Hmm.. Thinking some more about it, I think that what would actually
work really well at least for the kernel is:
(a)
This commit introduces a new module_switch_driver macro, similar to
module_platform_driver and such, to reduce boilerplate when declaring
DSA switch drivers.
In order to use the module_driver macro, register_switch_driver needed
to be changed to return an int instead of void, so make it return 0.
Use the module_switch_driver helper macro to declare the driver and thus
reduce boilerplate.
