Hi,
Here's a bunch of clean up patches for WMI and a
single fix. I'm including the fix in this patchset
because one of the clean up patches depends on it.
Michal Kazior (9):
ath10k: fix tx/rx chainmask init
ath10k: remove unused pdev_set_channel command
ath10k: deduplicate wmi_channel code
ath10k: deduplicate host mem chunk code
ath10k: relocate wmi attach/deatch functions
ath10k: deduplicate wmi service ready logic
ath10k: clean up phyerr code
ath10k: unify wmi event function names
ath10k: re-work scan start command building

Like discussed in IRC, you don't need to resent the whole patchset just
because of this. I have now folded the patch below onto your patch in
ath-next-test, please review:

This command is not used anymore and most firmware

switching is done via vdev restarting.

Good catch. I'll fix that.

I don't think current firmware interface is capable of advertising
that to the host so I'm guessing there are none yet.

The structure is being set up in 2 places.
Deduplicate the code by creating a helper.

Looks good. Thanks!

Make all wmi event functions match the same naming
style, i.e. ath10k_wmi_event_<name>.

The logic responsible for processing the event is
no different across different firmware binaries.
The difference that needs to be dealt with is the
ABI of data structures.
The intermediate structure uses __le32 to avoid
extra memory allocations to byteswap
variable-length substructures (i.e. host mem
chunks).

Isn't this unneeded change?

Are there are no chips that support a different number
of tx and rx chains?

Firmware reports the number of RF chains so use
that for initialization of supp_{tx,rx}_chainmask
instead of using a macro for 3x3 chips.
This should make tx/rx chainmask reports correct
for chips other than 3x3.
