claude-noether 843d40231f danctnix-besser: regen cumulative patch with bes_chardev.{c,h} merge fix 
Build (PID 558898 on boltzmann) failed at bes2600_btuart.c:81:
  error: implicit declaration of function 'bes2600_chrdev_switch_subsys_glb'

Root cause: the original danctnix-flavor adaptation overlaid Mobian's
heavily-trimmed bes_chardev.{c,h} on top of pristine danctnix.  Mobian's
flavor (694 lines) had stripped out the BT/WiFi subsystem-switch
orchestration that pristine danctnix (1387 lines) carries and that
danctnix-only bes2600_btuart.c calls.

Fix: restore pristine danctnix bes_chardev.{c,h} as the baseline for
those two files in the danctnix flavor, then reapply Mobian's
campaign-relevant changes:
  - Patch G: SPDX-License-Identifier header + corrected attribution
  - Patch B: bes2600_chrdev_do_bus_reset + _trigger_bus_reset
    (definitions in bes_chardev.c, declarations in bes_chardev.h,
    EXPORT_SYMBOL_GPL on _trigger_bus_reset since it is called from
    sta.c connection-loss-storm fast-recover path)

Phase 6 thread-safety contract: bus_reset functions read
bes2600_cdev.{sbus_ops,sbus_priv} without locking, identical to the
Mobian-flavor source-of-truth - acceptable given the bus_reset is
invoked from already-serialized higher-level error paths in sta.c.

48 files unchanged in count, +1412/-1243 (was +1426/-2003).  The
delta vs the previous patch is concentrated in bes_chardev.{c,h}:
+776/-16 in .c (restoring the BT/WiFi switching infrastructure plus
appending Patch B), +2/-2 in .h (declarations + SPDX).

Patch verified to apply cleanly to v7.0-danctnix1 baseline.
b2sum updated in PKGBUILD.

Build retrigger pending on his.

claude-noether 6ab61b9a06 danctnix-besser-pkgbuild: linux-pinetab2-danctnix-besser PKGBUILD + cumulative bes2600 patch 
Soft-upstream candidate for DanctNIX.  Drop-in replacement for
linux-pinetab2 carrying the BESser bes2600 staging-driver patchset
(16 squashed commits from marfrit/bes2600-dkms cleanups branch,
adapted to danctnix-flavor).

Layout:
  README.md                                                — overview
  kernel/PKGBUILD                                           — patched fork of pine64/linux-pinetab2/PKGBUILD
  kernel/config                                             — danctnix kernel config (unchanged)
  kernel/0001-bes2600-besser-cumulative-series.patch        — 172 KB cumulative diff

Net diff vs danctnix v7.0-danctnix1: 48 files, +1426 / -2003 in
drivers/staging/bes2600/.

Squashed series:
  c5.1, c5.1.1, c5.2, c6.1, c6.2, c7, c5.2.1   (c-stack: scan-defer,
                                                PM-state-resync,
                                                firmware-PSM-skip,
                                                multi-func SDIO rescan)
  Patch A (decrypt-storm fast-recover)
  Patch B (connection-loss bus_reset)
  Patch F (cw1200 mainline backports)
  Patch C v3 (drop sdio_rx_work relay)
  Patch G (SPDX + ST-Ericsson attribution)
  Patch D (ba_lock atomicization)
  Patch E (ps_state_lock skip)
  Patch C2 (ieee80211_rx_irqsafe -> ieee80211_rx_ni)
  Patch H (bh.c hygiene cleanup)

Phase 7 on Mobian DKMS: +67% throughput vs Patch B baseline; race-fix
verified under stress.  Danctnix-flavor build verification deferred
to PKGBUILD CI.
