[PATCH wireless-next 0/7] wifi: brcmsmac: embed fixed-size allocations in brcms_c_info

[Rosen Penev <rosenp@gmail.com>]

brcms_c_attach_malloc() allocates struct brcms_c_info and then a number
of fixed-size structures that live exactly as long as it does, each with
its own kzalloc(GFP_ATOMIC), error code and kfree(). This series embeds
seven of them in their parent structures. That removes the allocations
and their OOM error paths and, for the per-band state, the open-coded
pointer arithmetic that carved two arrays out of one allocation.

Patch 1 embeds the per-band state arrays of brcms_c_info and
brcms_hardware. Patches 2-7 embed the module callback array, the MAC
statistics snapshot, the default BSS info, the protection settings, the
core state and the BSS configuration. Patch 7 moves the definition of
struct brcms_bss_cfg, unchanged, above struct brcms_c_info.

There is no functional change. The pub, hw and stf allocations are left
alone: embedding them would touch most of the driver for little gain.

Each patch builds with W=1 (arm64, clang) and passes checkpatch.
Compile-tested only.

An AI coding assistant (Claude Code, Claude Opus 5.5) was used to review
the series, resolve rebase conflicts, write patches 5-7, and draft the
commit messages and this cover letter.
