Subject: [PATCH] ath10k: Fix error handling in case of CE pipe init failure
Date:   Sat, 12 Dec 2020 00:30:10 +0530
Message-Id: <1607713210-18320-1-git-send-email-pillair@codeaurora.org>
Precedence: bulk

Currently if the copy engine pipe init fails for snoc based
chipsets, the rri is not freed.

Fix this error handling for copy engine pipe init
failure.

Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.1-01040-QCAHLSWMTPLZ-1

Fixes: 4945af5b264f ("ath10k: enable SRRI/DRRI support on ddr for WCN3990")
