I don't see patch 2 in patchwork and I assume discussion continues.
Apologies. I made sure to CC you individually on all the patches but
didn't think about the fact that you use patchwork to manage and so
didn't ensure all patches made it to all lists (by default each patch
gets recipients individually from get_maintainer). I'll make sure to
fix for patch set #2. If you want to see all the patches, you can at
least find them on lore.kernel.org linked from the cover:
Please resend if/when I need to apply something.
2 patches set to Changes Requested.
10948785 [1/3] brcmfmac: re-enable command decode in sdio_aos for BRCM 4354
As per Arend I'll change patch #1 to a full revert instead of a
partial revert. Arend: please yell if you want otherwise.
No yelling here. If any it is expected from Cypress. Maybe good to add them
specifically in Cc:
