Subject: drm/amd/display: Return a correct error value
Git-commit: 75441d9d35f71123933eafa4dd55459403582add
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
[why]
The function is expected to return instance of the timing generator
therefore we shouldn't be returning boolean in integer function,
and we shouldn't be returning zero so changing it to -1.
