The timeout is passed as a constant which makes it HZ dependent because
jiffies are expected so it should be converted to jiffies. The actual
value is not clear from the code - my best guess is that this should be
300 milliseconds given that other timeouts are in milliseconds based on
looking at other drm drivers (e.g. exynos_drm_dsi.c:356 300ms,
tegra/dpaux.c:188 250ms) - this needs to be confirmed by someone who
knows the details of the driver.

This was compile tested with qcom_defconfig +
CONFIG_DRM=m (implies CONFIG_DRM_MSM=m)
Patch is against 4.0-rc6 (localversion-next is -next-20150402)
