2019-05-31drm/bridge: tc358767: use more reliable seq when finishing LTTomi Valkeinen
At the end of the link training, two steps have to be taken: 1) tc358767's LT mode is disabled by a write to DP0_SRCCTRL, and 2) Remove LT flag in DPCD 0x102. Toshiba's documentation tells to first write the DPCD, then modify DP0_SRCCTRL. In my testing this often causes issues, and the link disconnects right after those steps. If I reverse the steps, it works every time. There's a chance that this is DP sink specific, though, but as my testing shows this sequence to be much more reliable, let's change it.

Link training will sometimes fail if the DP link is enabled when tc_main_link_enable() is called. The driver makes sure the DP link is disabled when the DP output is disabled, and we never enable the DP without first disabling it, so this should never happen.

2019-05-31drm/bridge: tc358767: fix tc_aux_get_status error handlingTomi Valkeinen
tc_aux_get_status() does not report AUX_TIMEOUT correctly, as it only checks the AUX_TIMEOUT if aux is still busy. Fix this by always checking for AUX_TIMEOUT.

2019-05-29drm/amdkfd: fix null pointer dereference on devColin Ian King
The pointer dev is set to null yet it is being dereferenced when checking dev->dqm->sched_policy. Fix this by performing the check on dev->dqm->sched_policy after dev has been assigned and null checked. Also remove the redundant null assignment to dev.

2019-05-28drm/amdgpu: Need to set the baco cap before baco resetEmily Deng
For passthrough, after rebooted the VM, driver will do a baco reset before doing other driver initialization during loading driver. For doing the baco reset, it will first check the baco reset capability. So first need to set the cap from the vbios information or baco reset won't be enabled.
