Hello,
I just noticed in 5.2.7+ kernel than this commit below appears to break WMI
message for my 10.1 firmware, and based on code inspection, 10.2 will be broken
as well.
10.1 struct ends with cycle_count, and 10.2 ends with one 32-bit number
after that, but which is not chan_tx_pwr_range.
I guess you need to create your own wmi msg for the WCN3990.
The change to 10.4 chan_info event is also wrong for my relatively
new version of 10.4 code, so likely breaks firmware in use. last member
in that struct in my 10.4 fw src is 'A_UINT32 rx_11b_mode_data_duration;'

Sorry, I mis-read this 10.4 part of the patch, it was not changing the wmi event
itself, so probably that part is fine.
Thanks,

Hi Ben,
Can you please check https://patchwork.kernel.org/patch/10844513/ ?
This change fixes the below mentioned regression. A different structure
is made for tlv specific event handling.
Thanks,
Rakesh Pillai.

Looks like it should work.
Why is this rotting in patchwork?
Thanks
