When releasing frames from the reorder buffer, the link ID was not
included in the RX status information. This subsequently led mac80211 to
drop the frame. Change it so that the link information is set
immediately when possible so that it doesn't not need to be filled in
anymore when submitting the frame to mac80211.

With debugfs=off, we can get here with the dbgfs_dir being
an ERR_PTR(). Instead of checking for all this, which is
often flagged as a mistake, simply handle the names here
more carefully by printing them, then we don't need extra
checks.
Also, while checking, I noticed theoretically 'buf' is too
small, so fix that size as well.

If we read txq->read_ptr without lock, we can read the same

to two different places, but crucially reclaim the same

Since the dump_data (struct iwl_fwrt_dump_data) is a union,
it's not safe to unconditionally access and use the 'trig'
member, it might be 'desc' instead. Access it only if it's
known to be 'trig' rather than 'desc', i.e. if ini-debug
is present.

"These mostly change the thermal core in a few ways allowing thermal
drivers to be simplified, in particular in their removal and failing
probe handling parts that are notoriously prone to errors, and
propagate the changes to several drivers.

Lake-M), some bugs are fixed and some code is cleaned up, as usual.

This release sees some exciting changes from David Lechner which
implements some optimisations that have been talked about for a long
time which allows client drivers to pre-prepare SPI messages for
repeated or low latency use. This lets us move work out of latency
sensitive paths and avoid repeating work for frequently performed
operations. As well as being useful in itself this will also be used in
future to allow controllers to directly trigger SPI operations (eg, from
interrupts).
Otherwise this release has mostly been focused on cleanups, plus a
couple of new devices:
- Support for pre-optimising messages.
- A big set of updates from Uwe Kleine-König moving drivers to use APIs
with more modern terminology for controllers.
- Major overhaul of the s3c64xx driver.
- Support for Google GS101 and Samsung Exynos850.

This is caused by a mistake in the chip initialisation. This version of

but the extra table is being loaded at the wrong time, in
rtw_chip_board_info_setup().
Move the extra AGC table loading to the right place, in

The rtw_chip_board_info_setup() can only do "software" things, and

Actually those buffers are used only by QMI target -> host communication.
And for WCN6855 and QCA6390, the largest packet size for that is less
than 6KB. So change buf_len field to 8KB, which results in order 1
allocation if page size is 4KB. In this way, we can at least save some
memory, and as well as decrease the possibility of allocation failure
in those scenarios.
