Subject: [PATCH] [PATCH] venus: core: remove CNOC voting while device suspend
Date:   Mon, 17 Feb 2020 17:31:31 +0530
Message-Id: <1581940891-2376-1-git-send-email-mansur@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

video driver is voting for CNOC during probe and not clear
while device suspend. Because of which XO shutdown is
happing(BCM42: VALID: 0x1 VOTE_X: 0x0000 VOTE_Y: 0x0004).

So, clearing CNOC voting while device suspend.
