Pull networking fixes from Jakub Kicinski:
 "Including fixes from can, bluetooth and wireless.

  No known regressions at this point. Another calm week, but chances are
  that has more to do with vacation season than the quality of our work.

  Current release - new code bugs:

   - smc: prevent NULL pointer dereference in txopt_get

   - eth: ti: am65-cpsw: number of XDP-related fixes

  Previous releases - regressions:

   - Revert "Bluetooth: MGMT/SMP: Fix address type when using SMP over
     BREDR/LE", it breaks existing user space

   - Bluetooth: qca: if memdump doesn't work, re-enable IBS to avoid
     later problems with suspend

   - can: mcp251x: fix deadlock if an interrupt occurs during
     mcp251x_open

   - eth: r8152: fix the firmware communication error due to use of bulk
     write

   - ptp: ocp: fix serial port information export

   - eth: igb: fix not clearing TimeSync interrupts for 82580

   - Revert "wifi: ath11k: support hibernation", fix suspend on Lenovo

  Previous releases - always broken:

   - eth: intel: fix crashes and bugs when reconfiguration and resets
     happening in parallel

   - wifi: ath11k: fix NULL dereference in ath11k_mac_get_eirp_power()

  Misc:

   - docs: netdev: document guidance on cleanup.h"

@@ -375,6 +375,22 @@ When working in existing code which uses nonstandard formatting make
 your code follow the most recent guidelines, so that eventually all code
 in the domain of netdev is in the preferred format.
 
+Using device-managed and cleanup.h constructs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Netdev remains skeptical about promises of all "auto-cleanup" APIs,
+including even ``devm_`` helpers, historically. They are not the preferred
+style of implementation, merely an acceptable one.
+
+Use of ``guard()`` is discouraged within any function longer than 20 lines,
+``scoped_guard()`` is considered more readable. Using normal lock/unlock is
+still (weakly) preferred.
+
+Low level cleanup constructs (such as ``__free()``) can be used when building
+APIs and helpers, especially scoped iterators. However, direct use of
+``__free()`` within networking core and drivers is discouraged.
+Similar guidance applies to declaring variables mid-function.
