Subject: [PATCH] ath10k: Fix channel info parsing for non tlv target
Date: Fri, 8 Mar 2019 16:56:06 +0530 [thread overview]
Message-ID: <1552044366-9186-1-git-send-email-pillair@codeaurora.org> (raw)
The tlv targets such as WCN3990 send more data in
the chan info event, which is not sent by the non tlv
targets. There is a minimum size check in the wmi event for
non-tlv targets and hence we cannot update the common
channel info structure.
If the common channel info structure is updated, the
size check for chan info event for non-tlv targets
will fail and return -EPROTO and we see the below
error messages
ath10k_pci 0000:01:00.0: failed to parse chan info event: -71
Add tlv specific channel info structure and restore the
original size of the common channel info structure to
mitigate this issue.
Tested HW: WCN3990
QCA9887
Tested FW: WLAN.HL.3.1-00784-QCAHLSWMTPLZ-1
10.2.4-1.0-00037
Fixes: 13104929d2ec ("ath10k: fill the channel survey results for WCN3990 correctly")
