[PATCH 02/17] drm/amd/display: Fixed bandwidth calculation error when converting fractions

[Harry Wentland]

From: Logatharshan Thothiralingam <logatharshan.thothiralingam at amd.com>

[Problem]
VSR greyed out

[Root cause]
When converting fractions, we were using the integer function, which let to
a large display clock and the view was not supported

[Solution]
Change the integer to fraction functions
