Subject: [PATCH 1/2] venus: core: change clk enable and disable order in resume and suspend
Date: Tue,  8 Sep 2020 09:14:05 +0530	[thread overview]
Message-ID: <1599536645-4593-1-git-send-email-mansur@codeaurora.org> (raw)

Currently video driver is voting after clk enable and un voting
before clk disable. Basically we should vote before clk enable
and un vote after clk disable.

Corrected this by changing the order of clk enable and clk disable.
