Subject: [PATCH] brcmfmac: wrap brcmf_fws_(de)init into bcdc layer

From: Rafał Miłecki <[email protected]>

fwsignal is only used by bcdc. Create new protocol interface functions
for core code to perform proto specific (de)initialization. This makes
core agnostic to the protocol which will allow further optimizations.
We will be able to avoid compiling unused protocols or modularize them.

You could see it like that, but no. These two patches were already
reviewed and I requested more testing as explained in another email
response. Your patch needed a bit of rework and you can safely assume
that my remarks on your patch would make it even more like the one we
already had queued up. So it seemed unreasonable to have Kalle apply
yours and then the two from Franky. It would only be for the sake of
kernel git stats, which is not something I want to factor in.

Arend

Given that your implementation (you now published) doesn't do any magic, is
there any real problem with my patch except of /not invented here/?

Thanks, Rafał

Franky had tackled this with two patches, which are queued to be submitted.
