commit cc78dc3b790619aa05f22a86a9152986bd73698c upstream.
This commit fixes the regression caused by commit 6ddc3860a566 ("ath10k: add support for ack rssi value of data tx packets") in linux-5.4.y branch.
ath10k_is_rssi_enable() always returns 0 for QCA9984 and this will cause the ppdu_info_offset to hold invalid value in ath10k_htt_rx_tx_compl_ind().
This leads to CE corruption for HTC endpoints to cause WMI command failures with insufficient HTC credits. Below warnings are seen due to beacon command failure in QCA9984.
[ 675.939638] ath10k_pci 0000:03:00.0: SWBA overrun on vdev 0, skipped old beacon [ 675.947828] ath10k_pci 0000:04:00.0: SWBA overrun on vdev 1, skipped old beacon
