Subject: [PATCH][next] drm/amd/display: fix incorrect assignment due to a typo

From: Colin Ian King <colin.king@...onical.com>

The assignment to infopacket->sb[7] looks incorrect, the comment states it
is the minimum refresh rate yet it is being assigned a value from the
maximum refresh rate max_refresh_in_uhz. Fix this by using min_refresh_in_uhz
instead.

Addresses-Coverity: ("Copy-paste error")
Fixes: d2bacc38f6ca ("drm/amd/display: Change infopacket type programming")
