[PATCH AUTOSEL 5.15 6/9] drm/amd/display: Reset freesync config before update new state

[Sasha Levin]

From: Tom Chung <chiahsuan.chung@amd.com>

[ Upstream commit 6b8487cdf9fc7bae707519ac5b5daeca18d1e85b ]

[Why]
Sometimes the new_crtc_state->vrr_infopacket did not sync up with the
current state.
It will affect the update_freesync_state_on_stream() does not update
the state correctly.

[How]
Reset the freesync config before get_freesync_config_for_crtc() to
make sure we have the correct new_crtc_state for VRR.

[PATCH AUTOSEL 5.15 7/9] drm/radeon: check bo_va->bo is non-NULL before using it

[Sasha Levin]

From: Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-prayer@amd.com>

[ Upstream commit 6fb15dcbcf4f212930350eaee174bb60ed40a536 ]

The call to radeon_vm_clear_freed might clear bo_va->bo, so
we have to check it before dereferencing it.
