drm/radeon/kms: fix tiling info on evergreen
We aren't currently using tiling in userspace on evergreen,
but the info we currently return for the tiling info query

ipv6: addrconf: don't remove address state on ifdown if the address is being kept
Currently, addrconf_ifdown does not delete statically configured IPv6
addresses when the interface is brought down. The intent is that when
the interface comes back up the address will be usable again. However,
this doesn't actually work, because the system stops listening on the
corresponding solicited-node multicast address, so the address cannot
respond to neighbor solicitations and thus receive traffic. Also, the
code notifies the rest of the system that the address is being deleted
(e.g, RTM_DELADDR), even though it is not. Fix it so that none of this
state is updated if the address is being kept on the interface.
Tested: Added a statically configured IPv6 address to an interface,
started ping, brought link down, brought link up again. When link came
up ping kept on going and "ip -6 maddr" showed that the host was still
subscribed to there

drivers/video/backlight/adp8860_bl.c: fix ambient light zone overwrite handling
This affects the get/set of the current Ambient Light Zone. Reading
should return an integer between 1..3 (1 = Daylight, 2 = office, 3 =
dark). Writing a value between 1..3 forces the backlight controller to
enter the corresponding Ambient Light Zone. Writing 0 returns to normal
operation.
Fix valid range checking so we don't write invalid values to the
controller, and make sure we subtract 1, since this is what the register
definition (CFGR:BLV) requires. Otherwise the values written don't work
correctly.

backlight: add low threshold to pwm backlight
The intensity of the backlight can be varied from a range of
max_brightness to zero. Though most, if not all the pwm based backlight
devices start flickering at lower brightness value. And also for each
device there exists a brightness value below which the backlight appears
to be turned off though the value is not equal to zero.
If the range of brightness for a device is from zero to max_brightness. A
graph is plotted for brightness Vs intensity for the pwm based backlight
device has to be a linear graph.
intensity
| /
| /
| /
|/
---------
0 max_brightness
But pratically on measuring the above we note that the intensity of
backlight goes to zero(OFF) when the value in not zero almost nearing to
zero(some x%). so the graph looks like
intensity
| /
| /
| /
| |
------------
0 x max_brightness
In order to overcome this drawback knowing this x% i.e nothing but the low
threshold beyond which the backlight is off and will have no effect, the
brightness value is being offset by the low threshold value(retaining the
linearity of the graph). Now the graph becomes
intensity
| /
| /
| /
| /
-------------
0 max_brightness
With this for each and every digit increment in the brightness from zero
there is a change in the intensity of backlight. Devices having this
behaviour can set the low threshold brightness(lth_brightness) and pass
the same as platform data else can have it as zero.
