[why & how] When the commit 9d84c7ef8a87 ("drm/amd/display: Correct cursor position on horizontal mirror") was introduced, it used the wrong calculation for the position copy for X. This commit uses the correct calculation for that based on the original patch.

Hey,
AFAIU, this patch reverts the change in the previous patch. Or this should be discarded, or both.
Hi Melissa,
This is a different part of the same function; the above change happens toward the end of dcn10_set_cursor_position, and your change occurs in the middle of the function. I think your change can probably be applied in this second part, but I prefer to do it in a different patch since this other change requires validation.
Thanks Siqueira
Melissa
