Subject: [PATCH] brcmfmac: simplify building interface combinations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Move similar/duplicated code out of combination specific code blocks.
This simplifies code a bit and allows adding more combinations later.
A list of combinations remains unchanged.
