claude-noether fd0f5a8b71 danctnix-besser: replace cumulative patch with per-series (pkgrel=4)
Replace the single squashed 0001-bes2600-besser-cumulative-series.patch
with 20 individual per-commit patches matching the bes2600/besser-danctnix-v3
branch in marfrit/bes2600-dkms.  Also remove the duplicate 0003-arm64 entry
that was a bug in pkgrel=3.

Patch list:
  0001 c5.1   defer scan and soften WARN on firmware reject
  0002 c5.1.1 widen scan-defer backoff to 30s and decay reject_count
  0003 c5.2   recover wedged firmware via mmc_hw_reset on link break
  0004 c6.1   gate PM indication completion on pending request
  0005 c6.2   short-circuit wake handshake when chip confirmed ACTIVE
  0006 c7     self-detect when firmware does not honor PSM and skip
  0007 c5.2.1 handle multi-function SDIO cards in mmc_hw_reset
  0008 Patch A pre-empt AP-deauth-6 with reassoc on decrypt-fail storm
  0009 Patch B bus_reset on connection-loss storm
  0010 Patch F3 atomicize atomic_add() calls
  0011 Patch F2 fix missing destroy_workqueue() on error in init_common
  0012 Patch F1 fix concurrency UAF in bes2600_hw_scan / sched_scan
  0013 Patch C v3 drop sdio_rx_work relay, IRQ→bh-direct
  0014 Patch G restore SPDX identifiers + ST-Ericsson attribution
  0015 Patch D atomicize ba_lock counters, drop the spinlock
  0016 Patch E skip ps_state_lock when PSM-known-disabled
  0017 Patch C2 replace ieee80211_rx_irqsafe with ieee80211_rx_ni
  0018 Patch H bh.c hygiene cleanup (drop fossil blocks, dead stubs)
  0019 besser#18 pending_record_lock SOFTIRQ-safe fix
  0020 danctnix-flavor: export bus_reset helpers for bes2600_btuart

Build pending (pkgrel=4 makepkg in progress on boltzmann).

Subject: [PATCH 10/20] bes2600: replace a set of atomic_add()
Backport of cw1200 mainline commit 07f995ca1951 ("cw1200: replace a set
of atomic_add()", 2020-11-10). atomic_inc() reads more naturally than
atomic_add(1, &x). Mechanical change, no functional impact.
7 sites: 6 in bh.c (bh_term, bh_rx x2, bh_tx x3) and 1 in itp.c
(awaiting_confirm). Two of the bh_rx and three of the bh_tx sites are
inside the cw1200-ancestor #if 0 block; replaced anyway to keep the
file consistent with cw1200 mainline source style.
Cherry-picked from upstream Linux:
