b43 wireless driver included internal implementation of cordic
algorithm which has now been removed in favor of library
implementation.

During the process, brcmfmac was driver was also cleaned.

Please note that this series is only compile-tested, as I
do not have access to the hardware.

Priit Laes (5):
  lib: cordic: Move cordic macros and defines to header file
  brcmfmac: Use common CORDIC_FLOAT macro from lib
  brcmfmac: Drop unused cordic defines and macros
  b43: Use common cordic algorithm from kernel lib
  b43: Drop internal cordic algorithm implementation

I don't see patch 1 in linux-wireless patchwork:

https://patchwork.kernel.org/project/linux-wireless/list/?series=38033&state=*

Via which tree are you planning to push these? These could potentially
go via my wireless-drivers-next tree (if review goes ok) but I need to
have all five patches in patchwork.

Also I don't see MAINTAINERS entry for cordic.[c|h], that would be good
to have as well.

Oh, forgot to mention that please resubmit all five patches, not just
patch 1, because then it's easier for me to apply them.

We added the cordic library functions during brcm80211 staging cleanup. 
We can add it to MAINTAINERS file.

You actually touched the *brcmsmac* driver, not brcmfmac. Please fix the 
driver prefix where appropriate in this series, ie. patches 2 and 3.

I can/will verify brcmsmac. As Kalle mentioned it makes more sense to 
push the 'lib: cordic:' patch through the wireless tree as well as it 
only is used by wireless drivers right now.

Arend

Great, thanks.
