[Why] link_stream is never NULL here as we've dereferenced it a couple lines before and have done so for a couple months now. [How] - Drop the NULL check. - Initialize where we know link_stream is non-NULL Signed-off-by:

[why] When the system is going into suspend, set_backlight gets called after the eDP got blanked. Since smooth brightness is enabled, the driver will make a call into the DMCU to ramp the brightness. The DMCU would try to enable ABM to do so. But since the display is blanked, this ends up causing ABM1_ACE_DBUF_REG_UPDATE_PENDING to get stuck at 1, which results in a dead lock in the DMCU firmware. [how] Disable brightness ramping when the eDP display is blanked. Signed-off-by:

[Why] Specifically to one panel, TCON is able to accept active video signal quickly, but the Source Driver requires 2-3 frames of extra time.

[Why] For DCE110, DCE112 and DCE120 the max_clks_by_state for the clk_mgr are copied from their respective table before the call to dce_clk_mgr_construct, but then dce_clk_mgr_construct overwrites these with the dce80_max_clks_by_state.

[Why] Fixes issue when we have a display connected using a passive dongle and then emulate over it using a DP connection at 1 x 1.62 Ghz. System hangs because register bus returns back 0xFFFFFFFF for all register reads after setting register DIG_BE_CNTL in dcn10_link_encoder_connect_dig_be_to_fe(). Hang occurs later when trying to do a register read. [How] At the start of the emulation, dc_link_set_preferred_link_settings() and dp_retrain_link_dp_test() is called, even though it is connected using a passive dongle. Add an extra condition in dp_retrain_link_dp_test() to check for link->dongle_max_pix_clk > 0. This is the only way we know if the connection is using passive dongle so we don't retrain DP.
