  patches to clean all of this up in 5.12.

continue using them for the moment.

Unfortunately, we require some hacks to do so, as the BeforeLinkTraining
IED script became a pointer to an array of scripts instead, without a
revbump of the relevant tables.

There's also some changes to SOR clock divider fiddling, which are
hopefully correct enough that things work as they should.

AFAIK, GA100 shouldn't have display, so it hasn't been added.

2f0fa789f7 drm/amd/display: Fix to be able to stop crc calculation
[Why]
Find out when we try to disable CRC calculation, crc generation is still
enabled. Main reason is that dc_stream_configure_crc() will never get
called when the source is AMDGPU_DM_PIPE_CRC_SOURCE_NONE.

[How]
Add checking condition that when source is
AMDGPU_DM_PIPE_CRC_SOURCE_NONE, we should also call
dc_stream_configure_crc() to disable crc calculation.

25537d71e2 net: Allow NETIF_F_HW_TLS_TX if IP_CSUM && IPV6_CSUM
Cited patch below blocked the TLS TX device offload unless HW_CSUM
is set. This broke devices that use IP_CSUM && IP6_CSUM.
Here we fix it.

Note that the single HW_TLS_TX feature flag indicates support for
both IPv4/6, hence it should still be disabled in case only one of
(IP_CSUM | IPV6_CSUM) is set.

Fixes: ae0b04b238 ("net: Disable NETIF_F_HW_TLS_TX when HW_CSUM is disabled")

70db767fb3 Merge branch 'maintainers-remove-inactive-folks-from-networking'
To make maintainers' lives easier we're trying to nudge people
towards CCing all the relevant folks on patches, in an attempt
to improve review rate. We have a check in patchwork which validates
the CC list against get_maintainers.pl. It's a little awkward, however,
to force people to CC maintainers who we haven't seen on the mailing
list for years. This series removes from maintainers folks who didn't
provide any tag (incl. authoring a patch) in the last 5 years.
To ensure reasonable signal to noise ratio we only considered
MAINTAINERS entries which had more than 100 patches fall under
them in that time period.

All this is purely a process-greasing exercise, I hope nobody
sees this series as an affront. Most folks are moved to CREDITS,
a couple entries are simply removed.

The following inactive maintainers are kept, because they indicated
the intention to come back in the near future:

 - Veaceslav Falico (bonding)
 - Christian Benvenuti (Cisco drivers)
 - Felix Fietkau (mtk-eth)
 - Mirko Linder (skge/sky2)

Patches in this series contain report from a script which did
the analysis. Big thanks to Jonathan Corbet for help and writing
the script (although I feel like I used it differently than Jon
may have intended ;)). The output format is thus:

 Subsystem $name
  Changes $reviewed / $total ($percent%)           // how many changes to the subsystem had at least one ack/review

054c4610bd MAINTAINERS: dccp: move Gerrit Renker to CREDITS
As far as I can tell we haven't heard from Gerrit for roughly
5 years now. DCCP patch would really benefit from some review.
Gerrit was the last maintainer so mark this entry as orphaned.
