Currently in the case where some of the allocations fail for dce110_tgv, dce110_xfmv, dce110_miv or dce110_oppv then the exit return path ends up leaking allocated objects. Fix this by kfree'ing them before returning. Also re-work the comparison of the null pointers to use the !ptr idiom.

While validation fbc, array_mode of the pipe is accessed without checking plane_state exists for it. Causing to null pointer dereferencing followed by reboot when a crtc associated with external display(not connected) is page flipped. This patch adds a check for plane_state before using it to validate fbc. Signed-off-by:

Within atomic check, dm_update_crtcs_state is called twice. First to remove from the dc_state, and subsequently to add to it. In both calls, a secondary mode-change check is done using dc-level states. We shouldn't be doing this while removing, since a new dc_stream_state has not been created to do the necessary comparison. Because of this, the mode_changed flag within the DRM state can be mistakenly set to false. Doing so only when adding prevents this. We are also guaranteed that a call to add will come after remove, or else the atomic check fails (and a commit will not happen). Signed-off-by:

For DP active dongles, the dpcd dongle caps are read but not used to validate mode timing. This addresses this. In particular, this change fixes light up on the HDMI 4k TV connected through DP active dongle. Since the 4k TV defaults to YCbCr420, which the dongle don't support. This change does not address MST cases, a more generalized approach must be taken for that. Signed-off-by:
