Subject: [PATCH 0/6] Rockchip DRM use-after-free & null-ptr-deref fixes

The first three patches in the series are fixes for use-after-free &
null-ptr-deref related issues found in dw_dp and inno-hdmi Rockchip DRM
drivers.

The remaining ones provide a few minor improvements to dw_dp and
dw_hdmi_qp.
