In case of msm drm bind failure, pm runtime put sync
is called from dsi driver which issues an asynchronous
put on mdss device. Subsequently when dpu_mdss_destroy
is triggered the change will make sure to put the mdss
device in suspend and clearing pending work if not
scheduled.
Changes in v2:
- Removed double spacings [Jeykumar]
Changes in v3:
- Fix clock on issue during bootup [Rajendra]
Signed-off-by: Jayant Shekhar <jshek...@codeaurora.org>
So I no longer see the clock usecount mismatch with this patch now,
that I had earlier reported with the v2.
