patches/driver/bes2600: mirror besser series (closes #2)

Mirrors all 30 BES2600 patch series from marfrit/besser/patches/ into the kernel-agent scope-tagged tree under patches/driver/bes2600/. 15 base series + 15 -danctnix siblings = 45 .patch files including cover letters. Per-series promotion eligibility tracked in the README (default unset → ka-promote asks before including in a build). Markus to update as series mature. DKMS-to-in-tree transition path documented (drop bes2600-dkms once series lands in mainline / DanctNIX base). Cumulative-patch ordering caveat captured: existing order is NOT alphabetical (A,B,C v3,F,G,D,E,C2,c5.x,c6.x,c7,H). ka-promote needs an explicit apply_order field, not a series-name sort. Surface when fleet/ohm.yaml lands in #5. Acceptance criteria from #2: [x] All series present under driver/bes2600/ [x] Promotion eligibility per series (table in README, defaults unset for Markus to fill) [ ] Manifest for ohm references driver:bes2600 scope (deferred to #5) [x] DKMS-to-in-tree transition path documented Generated-by: Claude Opus 4.7 <claude@reauktion.de>

+Subject: [PATCH] bes2600: demote 'wait pm ind timeout' from bes_err to
+ bes_devel
+
+bes2600_pwr_enter_lp_mode() logs 'wait pm ind timeout' at bes_err
+level every time wait_for_completion_timeout() on the firmware's
+PM-change indication returns 0. The preceding patch ('bes2600:
+gate device LP-mode entry on successful per-VIF firmware
+handshake') already handles this case correctly: the per-VIF
+timeouts counter is incremented, the function returns
+-ETIMEDOUT, and the device-side LP transition is skipped -- the
+cascade into sdio_tx_work splats and [RX] Receive failure
+messages is prevented.
+
+The timeout itself is benign steady-state noise on the PineTab2
+(BES2600WM). Firmware occasionally misses the 5 s PM-change
+deadline when mac80211 flips power-save rapidly during
+association or roaming; observed rate on a quiet, associated
+ohm is roughly 3-10 events per 10 min of uptime, with no
+user-visible effect. Keeping it at bes_err() level (== KERN_ERR,
+priority 3) floods dmesg with what is already a handled
+condition and makes real SDIO / PM errors harder to spot.
+
+Demote to bes_devel() (== KERN_DEBUG gated on the driver's debug
+flag). The gate in the caller is unchanged, so the downstream
+suppression behaviour introduced by the earlier patch remains.
+Real pathologies -- bes_err("set operation mode fail") on the
+same path, and the timeouts != 0 / -ETIMEDOUT return consumed
+by callers -- still surface at bes_err() / return-value level.
