Subject: [PATCH] brcmfmac: slightly simplify building interface combinations

This change reorders some operations in brcmf_setup_ifmodes in hope to
|
|
make it simpler:
|
|
1) It allocates arrays right before filling them. This way it's easier
|
|
to follow requested array length as it's immediately followed by
|
|
code filling it. It's easier to check e.g. why we need 4 entries for
|
|
P2P. Other than that it deduplicates some checks (e.g. for P2P).
|
|
2) It reorders code to first prepare limits and then define a new combo.
|
|
Previously this was mixed (e.g. we were setting num of channels
|
|
before preparing limits).
|
|
3) It modifies mbss code to use i variable just like other combos do.
