def3488eb0 drm/amd/display: refactor HPD to increase flexibility
Currently all dcn revisions have to follow the same codepath for
hotplug detection. This change allows per dcn hpd handling consolidating
hpd code in link_encoder.

53c271b9a0 drm/amd/display: Remove redundant ternary operators
For ternary operators in the form of "a ? true : false" or
"a ? false : true", if 'a' itself returns a boolean result, the ternary
operator can be omitted. Remove redundant ternary operators to clean up the
code.

b0814fa3be drm/amd/display: Remove useless assignments and variables
[WHAT & HOW]
misc0, temp and split_pipe are assigned but immediately re-assigned
to other values. The early assignments are useless and are removed.
Unused variables are removed as well.

This fixes 5 UNUSED_VALUE issues reported by Coverity.
