Hi Bruce,

Those three patches are from mainline kernel without any change.
They exist since v5.3-rc4. Please help to backport to linux-yocto v5.2.

The second commit fixes the following calltrace.

  Call Trace:
    dump_stack+0x4f/0x6a
    ? worker_thread+0xd9/0x3e0
    ___might_sleep.cold+0xd1/0xe2
    __might_sleep+0x4b/0x80
    mutex_lock+0x21/0x50
    iwl_mvm_rs_rate_init+0x87/0xc50 [iwlmvm]

Gregory Greenman (3):
  iwlwifi: mvm: add a wrapper around rs_tx_status to handle locks
  iwlwifi: mvm: replace RS mutex with a spin_lock
  iwlwifi: mvm: fix possible out-of-bounds read when accessing lq_info
