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 following three patches provide a few minor improvements to dw_dp and dw_hdmi_qp, while the remaining two address use-after-free and memory allocation in DW DP core library.
