4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anilkumar Kolli <akolli@qti.qualcomm.com>
commit 4ad24a9d83bd4bf0a85e95bf144e18d3fda4fbf1 upstream.
It is observed that while loading and unloading ath10k modules
in an infinite loop, before ath10k_core_start() completion HTT
rx frames are received, while processing these frames,
dereferencing the arvifs list code is getting hit before
initilizing the arvifs list, causing a kernel panic.
This patch initilizes the arvifs list before initilizing htt.
Fixes the below issue:
[<bf88b058>] (ath10k_htt_rx_pktlog_completion_handler+0x278/0xd08 [ath10k_core])
[<bf88b058>] (ath10k_htt_rx_pktlog_completion_handler [ath10k_core])
[<bf88c0dc>] (ath10k_htt_txrx_compl_task+0x5f4/0xeb0 [ath10k_core])
[<bf88c0dc>] (ath10k_htt_txrx_compl_task [ath10k_core])
[<c0234100>] (tasklet_action+0x8c/0xec)
