I have been seeing lockdep asserts for a couple of months and finally found time to debug and fix the problems. The dmesg looks clean with these fixes. Enabling LOCKDEP and ATH10K_DEBUGFS triggers the lockdep assert and RCU warns. The first two patches in this series are fixes to lockdep assert and RCU usage bugs. The last patch (5/5) is a fix to reduce invalid ht params rate message noise. Patch 3/4 changes a message from debug to warn. Patch 4 adds detect to assert not calling ath10k_drain_tx() holding conf_mutex.
