This fixes the following error when building for arm-imx:
> ERROR: "__clk_get_name" [drivers/staging/imx-drm/ipu-v3/imx-ipu-v3.ko] undefined!
> make[1]: *** [__modpost] Error 1
> make: *** [modules] Error 2
There are valid usecases to get the name of a clock, be it for debugging
purposes or to register a children of a clock like done in this IPU driver.
Therefore exporting __clk_get_name() and make it available for others makes
sense.

Subject: [PATCH] mac80211: improve latency and throughput while software
scanning
Patch vastly improve latency while scanning. Slight throughput
improvements were observed as well. Is intended for improve performance
of voice and video applications, when scan is periodically requested by
user space (i.e. default NetworkManager behaviour).
Patch remove latency requirement based on PM_QOS_NETWORK_LATENCY,
this value is 2000 seconds by default (i.e. approximately 0.5 hour !?!).
Also remove listen interval requirement, which based on beaconing and
depending on BSS parameters. It can make we stay off-channel for a
second or more.
Instead try to offer the best latency that we could, i.e. be off-channel
no longer than PASSIVE channel scan time: 125 ms. That mean we will
scan two ACTIVE channels and go back to on-channel, and one PASSIVE
channel, and go back to on-channel.
Patch also decrease PASSIVE channel scan time to about 110 ms.
As drawback patch increase overall scan time. On my tests, when scanning
both 2GHz and 5GHz bands, scanning time increase from 5 seconds up to 10
seconds. Since that increase happen only when we are associated, I think
it can be acceptable. If eventually better scan time is needed for
situations when we lose signal and quickly need to decide to which AP
roam, additional scan flag or parameter can be introduced.
I tested patch by doing:
while true; do iw dev wlan0 scan; sleep 3; done > /dev/null
and
ping -i0.2 -c 1000 HOST
on remote and local machine, results are as below:
* Ping from local periodically scanning machine to AP:
Unpatched: rtt min/avg/max/mdev = 0.928/24.946/182.135/36.873 ms
Patched: rtt min/avg/max/mdev = 0.928/19.678/150.845/33.130 ms
* Ping from remote machine to periodically scanning machine:
Unpatched: rtt min/avg/max/mdev = 1.637/120.683/709.139/164.337 ms
Patched: rtt min/avg/max/mdev = 1.807/26.893/201.435/40.284 ms
Throughput measured by scp show following results.
* Upload to periodically scanning machine:
Unpatched: 3.9MB/s 03:15
Patched: 4.3MB/s 02:58
* Download from periodically scanning machine:
Unpatched: 5.5MB/s 02:17
Patched: 6.2MB/s 02:02
