[PATCH v3 0/2] Rockchip DRM use-after-free & null-ptr-deref fixes

[Cristian Ciocaltea]

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.
