wait_for_completion_timeout() returns 0 on timeout and aleast 1 otherwise
so checking for < makes no sense here.

Problem located with an experimental coccinelle script
While this check does no harm in this form - it should be fixed anyway
to comply with the API see: kernel/sched/completion.c
Also noticed that get_maintainer.pl will not list linux-ker...@vger.kernel.org
when run on drivers/gpu/drm/msm/dsi/dsi_host.c - is that intentional ?
Patch was compile-tested with: qcom_defconfig (implies DRM_MSM_DSI=y)
Patch is against v5.1-rc6 (localversion-next is next-20190424)
